Team Server API - Retrieve revisions from branch

Hi everyone,

We are trying to use Team Server API to get revisions of a branch by following instruction at:

https://docs.mendix.com/apidocs-mxsdk/apidocs/team-server-api

For the mainline, we have:

https://deploy.mendix.com/api/1/apps/testmx6/branches/trunk/revisions

it works well.

However, for the branchs, for example:

https://deploy.mendix.com/api/1/apps/testmx6/branches/branch_2/revisions 

It doesn't work, and we got:

{"errorMessage": "There is no branch with name 'branch_2'.","errorCode": "BRANCH_NOT_FOUND"
}

Which is not correct since we check and the branch is there.

Do you know if it's bug of Mendix or if we do something wrong?

Best regards,
