Very difficult error; unexpected error writing points to database: [shard 12] unexpected end of JSON input, Docker Compose, need help

Nobody has claimed this yet.

I have been searching and experimenting for hours now. The problem is that in my docker compose project i cannot send data from nodered to influxdb anymore. Everythig used to work fine. But, after letting the containers run for 3 days, it stopped working. Docker daemon couldnt start up anymore. After research, I came to the conclusion that there was not enough storage left, which ended up being the case. So, i checked what was using so much space and truncated the docker container that used up most space (it was 46Gb somehow and i have 55GB in total). This somehow solved the issue of docker daemon not starting up. However, after succesfully starting up the containers I got the following error message in nodered.

error message in nodered, regarding influxdbout node;
"HttpError: unexpected error writing points to database: [shard 12] unexpected end of JSON input"

I checked the container logs of influxdb;
repeated lines in the influxdb container logs;

removing all containers by doing docker compose down and then up again sadly doesn't work... I feel like im so fcked right now, because this is part of my bachelor's project... I didn't expect this to come up

extra info; im working on a debian linux 11 environment. I only have acces to this computer via ssh

This is a diagnosis request rather than a scoped code change, and it names no source file or test. Start by reviewing the Docker Compose setup, the Node-RED influxdbout node, and the InfluxDB container logs for shard 12; done would require identifying a reproducible cause and a verified recovery or fix.
