BP 7.1 edge extension problem

MaurizioTranqui — Fri, 29 Jul 2022 08:45:00 GMT

Hi, I have a problem with integrating BP with EDGE. In my company we have upgraded to 7.1 as we can no longer use IE.
Unfortunately I can't get BP to work with EDGE or CHROME.
When I launch the web based application, BP returns the error "The browser extension was not detected ...".
I followed the steps below and checked:
1. Browser extension compatibility
2. The windows registry keys
3. The manifest files installed in the registry
4. BP's MessageHost.exe called by the manifest
5. Edge extension starts correctly (browser icon)

I believe that everything is correctly configured, but I do not understand where the error is (the event manager does not report any errors).
The problem is probably with the PC but I can't see where it is.

BP: 7.1
Application Manager: 7.1.0.62280
.Net: 4.7
Edge: 103.0.1264.77
extension: 7.1.0.59613 (ID: alphbcchbekpcafaknckinfpapdaiiol)

Hi,

Did you check the following?
- MS Edge Startup boost setting, which should be disabled.
- MessagingHost.exe from the task manager that it comes up whenever the browser is launched and stays running as long as the browser is alive.
- Group policy and Security policy of the company.

I have gone through the same issues very recently and it turned out that all the issues were related with policies.

Best regards

Hello,

what action do you use for closing browser? We've had the same issue with using "Kill process" action for closing the browser. Since we started to using "Close browser" action the issue was gone.

Hope this will help you too.

Hi ,
the second point of list fail.
The process remain active for few second. (have you an idea to log the error?)
I also immediately thought about policy group problems, but I should understand what to report to the IT Department.

Hi Maurizio,

I'm not certain I understand all the things you said you checked, but some things I've seen cause this error are:

1. Modeller is still set to use IE and not pointed to the chromium browser
2. Extension isn't enabled in the browser (it might show installed, but is the slider set to enabled?)
3. You're running it under a different user and that user doesn't have the extension enabled/installed (we've seen where if a bot account is on a machine and that account doesn't have internet access, the extension doesn't always install/load until someone with internet access logs on to that machine)
4. There's a browser timeout setting somewhere in the desktop configurations, I believe, that can be extended past the default to allow more time for the site to load

Many of these assume that when you run the launch action in BP the browser actually loads but you then get the extension error. I understand BP gives you the error, but does the browser come up? If not, maybe also confirm the path to your browser (in both the modeller and the launch stage, if used) is correct. Maybe you're in Program Files instead of Program Files (x86) or vice versa?

Dear Tranquilli

1. Please check out the Application log (not Blue Prism log) from the Event manager where we found an error message persisting whenever the Messaging Host comes up and killed. It was saying something like ".... Can't open objects for query \BaseNamedObjects\WmiProviderSubSystemHostJob. Calling process is not authorized to open this job....".

2. You can also view the extra log of the extension. This was not helpful for us but maybe worth to check out:

Hi, I found the errors as you described them.
Also following the guide you attached, I found this error when sending edge via BP
[5740: 6976: 0802 / 095718.026: ERROR: native_message_process_host.cc (347)] Error when writing to Native Messaging host: -101

thanks for all, now i see with IT department

Sorry I didn't see this answer.
Answer to all point.
1. No, i switch on EDGE (i also tried chrome)
2. Yes extension was installed (it was installed by BP and cannot be deactivated)
3. No, we have only one user
4. I don't think that is a problem. The browser come up very fast and the error occurs after a few seconds

Hi there,

We recently upgraded and have these same issues across our production environment. I'm in the process of exporting the policy report to start digging through and do a comparison to a working environment.

HongJoo, you said most of your issues were because of group policies. Do you know which policies were the problem?

Maurizio, were you able to find a solution for your issues?

Thank you,
Tj

We are experiencing the same issue and I've logged this with a BP ticket.

We have a number of user accounts we are testing this with over 3 different VM's. 1 user is a Domain admin in Azure and the rest are local admins on the machines. We can only get the browser to launch and not error as the domain admin. If we sign into a VM as a local admin account and launch, we get the error and MessagingHost.exe never starts. If we run Blue Prism on the same machine (still signed in as the local admin) as the domain admin user, the browser launches, MessagingHost.exe starts and the BP connects to the browser.

It appears to be a user permission issue to me, but we haven't got to the bottom of it yet,

Hi @Maurizio Tranquilli

Did you already have have had an update on this?

We recently have upgraded to V7.1 and as well are facing the error of the BP extension not being detected.

With kind regards,

We found that policies blocking access to command prompt, powershell and registry meant the extension couldn't be detected. If we relaxed these, we had no issues. We aren't sure at this point which one it was, but we have it working again.

Hi @Dan Lister

We have been able to resolve our issues. For us the fix was to grant our robot workers access to CMD.
Not sure on why the messaging host application needs to use CMD to successfully work? But access to CMD has resolved our issue!

Hi All,

Anyone found a standard solution for this issue ?

What we have noticed is - the moment Browser is launched, automatically "BluePrism.MessagingHost.exe" is getting triggered from backend.
But "BluePrism.MessagingHost.exe" is taking more time(20 Sec on an average) to come up in the task manager after Chrome is up.
So Blue Prism launch action is failing as "BluePrism.MessagingHost.exe" not coming up faster.

Note - If we launch browser manually then also "BluePrism.MessagingHost.exe" is getting triggered and showing up in Task Manager but with delay.

So, what we understand is the delay between Chrome and "BluePrism.MessagingHost.exe" is causing the problem.
We have tried updating all the Blue Prism Config file wait times but nothing helped.

Please share your thoughts. Thanks in advance.
And the strange thing here is - How come not a single response is available in this thread from Blue Prism Team member on this critical issue.

Thanks,
Sharath

This is a bit of a hack, but if manually starting the browser also causes the MessagingHost to launch, you could attempt the following.

Using Utility - Environment, use 'Start Process' to launch Chrome. Use the same starting URL data you normally would in your object's application model.
Using Utility - Environment, use 'Wait for Process' to check if BluePrism.MessagingHost.exe is running.
Have your object attach to an existing instance of Chrome. (This may require some additional configuration in your attach stage.)
