Blue Prism 7.3.1 Chrome problems.

Hi all,

We have just migrated from BP 7.0.2 to 7.3.1 and we got plenty of errors regarding Chrome operation. Those errors happen only when running with Blue Prism agent (control room)

I went through forum but it seems that no-one is facing similar problems so let me ask here.

1. "Wait22","Wait Start","ERROR: Internal : AMI error occurred in Wait Start Stage 'Wait22' on page 'Launch' - Object reference not set to an instance of an object.","2025/02/28 12:20:59"

It seems like the stage objects are not initialized properly, it happens since 7.3.1 in different stages, usually after retrying it works but sometimes it just does not recover.

Checked for the artifacts in code and tried respying the elements used in the stages but with no luck

2. "Attach","Navigate","ERROR: Internal : Failed to perform step 1 in Navigate Stage 'Attach' on page 'Attach' - Target application could not be identified, please ensure the application is running and review the following action inputs and/or application model identifiers: WindowTitle","2025/02/28 12:20:42"

This error also occurs randomly, we already did the fix for the V2 manifest. For now the person is checking the permission part as described here: could not open target process but I'm not sure if it's connected.

If anyone has any clue to the problems I described or had similar problems after migration please share in this post as well.

Cheers,
Hubert

@@Update

It seems we were able to mitigate the errors by adding static wait/sleep before actions.
I would appreciate if there is any other, more "proper" way to handle these sort of errors.
