Fail while pushing with --separate-weights

Today I started to face the following issue, while using cog push --separate-weights
Although I was able to push the model without the flag --separate-weights

On the error below, I just replaced the project and model name by and <model-name, respectively.

$ cog push --separate-weights

Start with the cog push --separate-weights path and reproduce the Docker build failure shown in the issue. Inspect Dockerfile line 2, where the -weights image is used, and the registry token request that returns 404. Done means pushing with --separate-weights completes without the failed metadata lookup or authorization error.
