Unactionable error while publishing to private gitlab registry

使用 --log-level trace 重现 issue 中的 devcontainer features publish 命令，重点关注 bearer-token 请求以及后续的标签列表请求。继续跟踪失败过程，直到暴露出可采取措施的 registry 错误，而不只是显示 Failed to publish；当该命令针对这个私有 registry 场景报告有用的诊断信息时，即表示完成。

Hi there. I couple of weeks ago I set up a repository of private devcontainer features on our gitlab instance and it did work pretty well.

Something has changed since then and I suspect it's probably on the side of the gitlab registry, but the error I'm getting does not allow me to investigate further, although I'm using the trace log level.

It tries to get the tag list, but then only fails with

[428 ms] (!) ERR: Failed to publish 'registry.taktsoft.com/taktsoft/devcontainers/features/collection-base'

Any idea on how I can get even more details about the error than just the trace log level?

Any help is much appreciated! ❤️

p.s.

We had to change the s3 backend for gitlab and decided to start with a completely empty registry instead of migrating the old bucket. No I idea if this could cause problems, but for other artifacts the registry works just fine.
