How can I debug this error?

(HTTP code 500) server error - invalid reference format 

The image successfully builds locally.

invalid reference format

This usually means something is wrong with the docker image name. What is the context for this error though?

[ekevu123]

Well, there was no context. It uploads the source tarball, gives it a build ID, and then this error happens.

[joseph]

@ekevu123 do you see anything in the build service app's logs itself?

When you run cloudron build, the first 3 lines would be interesting. It prints the full image name before uploading the tarball.

[ekevu123]

The first line is "using build service" and then the link.
The second line is "Building" followed by the repository name and the image tag.
Then it says "uploading source tarball"
Then it has a BuildID
and then the error comes

yes, here it seems there is something wrong with the name and image tag. I am not sure how to test for the validity of this (maybe chatgpt?) . But maybe you can see docker tag works locally (on some random test image)?

[ekevu123]

But how would I even be able to influence this? I think a recent change has caused that I can only run cloudron build and it doesn't take any arguments anymore? I think that behaviour used to be different. So, what else could I theoretically do except running cloudron build?

[joseph]

@ekevu123 you can set the repository name using cloudron build --set-repository . I think the args changed a bit, not sure exactly when.

[ekevu123]

True, it seems like the only things I can do are log out and log back in, and set the repository.
I am still unsure why it doesn't work for this one repository while it does work using docker build. I am happy to investigate this myself, but what is the difference between the two services exactly, except that one works on the server and the other locally? If I understood that, I would be happy to investigate.

docker build is building the image locally. cloudron build is pretty much doing the same thing but on a remote server. The code is at https://git.cloudron.io/packages/docker-builder-app/ . There is no difference other than what you already said.
