ubuntu server crash: reinstall teslamate docker

[manusaxo]

Hello to all

my Ubuntu server crashed, so I had to reinstall all the Docker containers.

Of course, I don't have any database backups, but I still have the volumes used by the various containers, and the files are intact.

I'm currently using the proposed compose and I realize that my database files are in V15 and not in V16.
I'm modifying my compose accordingly to be in postgres 15.

Next problem: I get an error when launching grafana because it doesn't have the rights to write to the volume. I'm correcting this problem temporarily by giving full access to the grafana volume folders. Grafana launches successfully.

I now have no data in grafana. The teslamate dashboards are present but no data is read. (No Data on each dashboard component) the error is as follows: A
Status: 500. Message: db query error: pq: invalid input syntax for type json

Where does this error come from?
Is there a procedure for redoing a clean installation by disposing of the files before crashing?

Thanks a lot in advance
