Want to confirm:

1. It seems that you are using gogit version.
2. When creating the mirror, did you select migrate the releases?

[h7su]

1. Yes，I didn't know there is another gitea before your answer, now I try the no gogit version, it works good, no error.
2. When i use the 'import outside repo' function from top-right, I just check 'use it as a mirror' , not seen 'migrate the releases'.
3. So, should this issue be treat as a bug?

[yp05327]

now I try the no gogit version, it works good, no error.

So only gogit version has this issue. Thanks for your test.

When i use the 'import outside repo' function from top-right, I just check 'use it as a mirror' , not seen 'migrate the releases'.

OK

So, should this issue be treat as a bug?

Not sure. Maybe caused by some special tags in this repo, like #28843 (comment)

[yp05327]

OK, I got it.

[yp05327]

The reason is that the creator is empty in tag v2.6.13-rc3

The reason is that the creator is empty in tag v2.6.13-rc3

So we have to use a ghost here if creator is empty.
