Can't create release with octo.exe 4.5.0

Hi there!
I think latest TFS extension have buggy octo.exe tool (4.5.0 version).
When I try to create release from TFS, I get error:
Error converting value "Variable" to type 'Octopus.Client.Model.DeploymentStepCondition'.

When I try to run octo.exe 4.45.0 version (got from with same arguments, everything runs OK.

Is there a solution to downgrade TFS extension? :slightly_smiling_face:

P.S. In my deployment process i have a step with
Run Condition: Variable

Hi Zygimantas,

Thanks for getting in touch and I’m sorry to hear that you are having these issues.

Can you send me the full TFS build log from the build that failed with that error to help us troubleshoot your issue.

Thank you and best regards,

Ok. I was trying to reproduce the bug and saw that there is new version of “Create Octopus release” 3.* task in TFS. Updated my build definition and the bug is gone.
Now i see that “Create Octopus Release” step is using octo.exe 4.45.0 version and there is no bug.

Just for reference, build log with old “Create Octopus Release” 2.* (using octo.exe 4.5.0):

I think this bug occurs when in your process you have step with Run Condition: Variable

Hi Zygimantas,

Great to hear that you were able to resolve this issue.

The error would be due to that the version of octo.exe in the old v2 extension does not support the Run Condition: Variable configuration as it was introduced in a later version of Octopus.

Thank you and best regards,
