Orchestrator and Robot / Error detecting project version

Hi,
I had a problem with the robot the last days after we updated UiPath Studio to v. 2019.10.1

On Orchestrator v. 2018.4.1 and v. 2018.4.4 (currently) there was a problem after starting the process:

Info: Error detecting project version

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults = true, whose value is:
System.Exception: Error detecting project version

I searched the forum and found a clue here:
Error detecting project version

In the project.json file, change the entry in the line:

“schemaVersion”: “4.0”,

to

“schemaVersion”: “3.2”,

but in the .nupkg process archive

For me, it is done in such a way that we have a test environment Orchestrator and a production Orchestrator.

I am moving a process package from one Orchestrator to another.

Having the package on the local disk, we run the archive, go to the directory: lib \ net45
search project.json and make changes.

We save the changes in the archive and install the package on the Production Orchestrator.

After starting the process, Robot does its job.

The fault lies with UiPath Robot on the production machine, which is older than UiPath Studio.

Kindly have a view on this thread
