Recently I added a few new Firebase projects, in the same way I normally do.
However, I can’t deploy to any of these projects.
I always get an error like this:

⠏ hosting[flock-sphv]: found 269 files in dist/spa
⠏ hosting: uploading new files [63/99] (63%)
Error: Task 6bf20f6cf051081b4f506440c118c0da5fd7ae67c6a887e6d1285f2a274848cd failed: retries exhausted after 6 attempts, with error: The “paths[1]” argument must be of type string. Received undefined
⠹ hosting: uploading new files [64/99] (64%)

Did I forget a step in my setup or is this a bug?
I can’t seem to find what causes the issue.
The percentage on which the errror occurs is always different.

Thanks in advance for the help!
