@takezoe Please Help Me.

Also, again this error is also observed for the repository:

Even I disabled all plugins, still the same problem persists.

Hmm, I can't reproduce the error so far. I want to understand your situation clearly first:

• The original repo works fine
• You forked that repo
• You see error in the forked repo

Is my understanding correct?

In that case, do you think if your source repo has any special characteristics? It would be really helpful if we have a procedure to reproduce the case from clean setup.

[takezoe]

I guess that error could happen when the default branch has no commit. I don't know how such situation happens but does this apply to your situation?

[tahaghafuri]

@takezone Yes, your understanding is correct. I also forked some repositories that have the same problem.

[takezoe]

Ah, you mean you created a repository on GitBucket by cloning from GitHub?

[tahaghafuri]

Yes

[takezoe]

I guess that error could happen when the default branch has no commit. I don't know how such situation happens but does this apply to your situation?

Looks like this is the root cause of your error because GitBucket's default branch is now main but the source repository you cloned doesn't have it.

Setting the default branch to master on GitBucket would eliminate the error.

I will consider if GitBucket can automatically adjust the default branch when a repository is created by cloning an external repository to avoid such confusion.

Thank you
