Hi,
I’ve been having a mystery failure when registering a new version of MultiGridBarrier.jl. Note that this package was working until this new version, and it’s just the registration that’s failing. I can’t figure out what’s going on because I’m not understanding the error message or it is lacking information. I also asked Claude and it is also baffled.
Anyone knows what’s going on?

From the AutoMerge log:

If you re-register the same commit, the CI jobs will be restarted. If this was an intermittent failure it might pass on a new attempt.

As per your suggestion, I relaunched the registration a couple of times in the 4 hours since you posted it. It keeps failing trying to reach: [https://conda.anaconda.org/conda-forge/noarch/repodata.json](https://conda.anaconda.org/conda-forge/noarch/repodata.json)
I was able to get this file in my shell on my laptop mac using curl. Is there something special about the github runners that make it unable to get this file? It is slightly large for a json file at 146.7MB or something like that.

That’s beyond my insights but there’s nothing stopping GitHub actions from having various limitations.
