Managing unable to detect browser extension

We are using BP 7.1

Occasionally launch fails to detect browser extension and the exception does not seem to be catch able.

If we

set tracking id data item to empty with calc stage
issue launch setting tracking id to data item
check if tracking id data item with decision stage

Can we use tracking id empty value to determine if launch failed without exception?

Hey Emmet,

I am not sure whats the behaviour when you mention 'not catchable'. Doesnt the process flows to appropriate recover stage?

Anyways, I faced something similar, what worked for me was waiting for the Blue Prism Messaging Process to be available. You may try this solution.

Environment Utility VBO - Action - Wait for Process - "BluePrism.MessagingHost" and have generous wait time configured in the action, before you launch the instance. Give it couple of retries, just in case.
