From what I’ve seen (https://github.com/cdr/code-server/issues/1136#issuecomment-549534426) the
joinerror is because the extension is missing files. You can try:But we need to look into our marketplace and figure out why this is failing to fully build. At least, I think that’s the source of the problem.
@code-asher @sr229 is there an update on this and similar issues with files missing in extensions downloaded from the Code Server marketplace?
