Error message from kopia

I have several kopia repositories that I have been using for about a year. Today kopia-ui showed one of the repositories as being not connected, and when I tried to reconnect I got the error message:

Connect Error: INTERNAL: internal server error: connect error: error connecting to repository: unable to list sources: unable to find manifest entries: unable to load manifest contents: error loading manifest content: error getting cached content from blob “q5328a0003e321c928460f18b2f906c46-s2bbbb62a3d5e164f13f”: failed to get blob with ID q5328a0003e321c928460f18b2f906c46-s2bbbb62a3d5e164f13f: BLOB not found

This repository is on my local filesystem, or actually on pCloud, which is mounted as a directory on my linux computer. I don’t see any problems with the pCloud directory itself. The size of the kopia subdirectory there is 1.2T.

Any suggestions?

Thanks,

Steve
