Error detecting project version-orchestrator

Hi All,

I have developed a script in Uipath 2019.10.1 version and published in orchestrator.
Then I executed from orchestrator which connected with the different robot with uipath version(2018.4.4)

It throws me below error:
Info: Error detecting project version

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

So only after upgrading to 2019 version process will execute successful or any other reason??

To solve for this, back up your project.json file, make note of all of the project dependencies, and then open your main workflow again. Re-download the packages you need for your project and the error should go away. The upgrade from 2018.4.4 to 2019.10.1 has different configuration settings, so you have to have UiPath studio rebuild the json file for it to work. The backed up json file can be used for reference on package dependencies and process arguments.

Did we check with this thread
