Check Config

It seems like something is wrong with the config in the Docker container. Are you using the default config? If you are, the config should be located in the container at /data/ipfs/config. Could you post the output from the command:

docker exec -ti <container_id> /bin/cat /data/ipfs/config 

If the IPFS repo is mounted outside of the container, then check for faults in the storage where the repo is mounted. If this is the case, them please run disk diagnostics to check for faults.

Error Detail

The error comes from here because the shard identifier above does not start with "/repo/flatfs/shard/".

Kubo calls this from the flatfs plugin, here, getting the shard identifier from the "shardFunc" parameter in the fsrepo datastore config. Normally the config should contain something like:

 "Datastore": {                                                                                                           
    "Spec": {                                                                                                              
      "mounts": [                                                                                                          
        {
