After upgrade from 3.4.14 to 3.5. We could not deploy a project to our development environment. (We use DTAP). We got the following error:
“An attempt to parse the variable symbol “variablename” appears to have resulted in a self referencing loop. Ensure that recursive loops do not exist in the variable values”
This variable was not used in the project that was being deployed. I found the “variablename” in our Library Variable set. But it wasn’t used recursively. The “variablename” was referenced in an other variable as part of the value of a connectionstring.
Then I noticed something. I deployed to our development environment. But the “variablename” did not have a scope for Development. I added a value for the “variablename” for the missing scope Development. I redeployed the package and it deployed successfully. The “variablename” was not new and was untouched for a few months.
First of all the error message is misleading, secondly the variable isn’t even used in the project that was deployed, so why did octopus reject my deployment. And last but not least the above was not present in the release of 3.4.14 and before, so something did change in the validation.
What are your thoughts about it?
The error message came from: https://github.com/OctopusDeploy/Octostache/blob/master/source/Octostache/Templates/EvaluationContext.cs
