Hi @tisonv, Thanks for the feedback. We suspect that the problem might be related to git extraheader, agent should remove it after the execution. Could you please check that the Agent have access to it with write permissions and you have nothing in it? Also could you please install a fresh agent from scratch to check will it works fine?

Hello @DmitriiBobreshev ! Thanks for the reply The account running the service is an admin of the collection. I guess it should have all the required permission by default. The 3.239.1 agent is installed by hand from the zip from github (no automated upgrade from Azure DevOps. Azure DevOps and the agent have very limited internet access)

I tested the 3.240.1 and the problem is no more. I suspect this has something to do with https://github.com/microsoft/azure-pipelines-agent/commit/04e4b9830a9582fbf5c5d9bbe7142caf4d9968e7 https://github.com/microsoft/azure-pipelines-agent/compare/v3.239.1...v3.240.1 There is no detail as why it was reverted though
