Is there an existing issue for the same bug?

• I have checked the existing issues.

Describe the bug and reproduction steps

The resolver fails at the "Create draft PR or push branch" step due to the following error:

Run if [ "true" == "true" ]; then

Seeing this as well.

@openhands-agent please investigate this by trying to write a test that fails with this error, and then fix the underlying problem.

[openhands-agent]

OpenHands started fixing the issue! You can monitor the progress here.

OK, I have examined this and it's confusing. For some reason the resolver is trying to apply a patch to a file that differs from the actual source file that was used to generate the patch. I'm not sure why this is happening, or what might have changed in our code to cause this to break now, given that the underlying code has not changed in several weeks. This needs further investigation. I'll assign to @malhotra5 but if I have time to take a look myself I will as well.
