Could not find source project from area path

[pelvark]

Hello,
I'm trying to run a migration of work items from one project to another, on two different devops accounts.
When I run the validation I get the following error:
[Info @08.35.44.264] Checking metadata for work item type Test Case [Info @08.35.44.264] Work item type Test Case validation completed successfully [Error @08.35.44.534] Validation error:. Could not find source project from area path Source Project\Project Area Path for work item with id 72580 [Info @08.35.44.539] Summary of errors and warnings: [Error @08.35.44.539] Validation error:. Could not find source project from area path Source Project\Project Area Path for work item with id 72580. Could not find source project from area path Source Project\Project Area Path for work item with id 72580

Looking in the code the following comment is at the validation error:
// This is a fatal error because this implies the query is cross project which we do not support, so bail out immediately

I'm not sure what this means, as the examples I've seen are all from one project to another.

I've tried making the same area path structure on the target project as it suggested by Mohamed Radwan in a comment on his guide. But it didn't change anything.

I found the problem,
because the project name had a space in it, I had used %20 in the config file to represent the space, as was done in the url of the devops project.
I changed this to be a normal space and didn't get the same error again.
