Pipeline Started Failing As a result of submodules

Using Jenkins Ask a question

We have a Jenkins Multi-branch pipeline which uses submodules. As at last week it was working, and then this week it stopped working all of a sudden. When I check the error message, this was what was displayed. I have updated all the plugins, restarted Jenkins but the issue still persisted. Does anyone know what might be going wrong?

I fixed the issue, Optional SSH Credential, someone added a ssh credential, which was confusing Jenkins because it was trying to use this for the submodules and it is not setup to use this. The main repo uses http and we have also setup the submodules to also use http and then adding this was conflicting things. This was never an issue before until now after we updated the plugins.
