Invalid type error

[temp]

We are seeing this in the docker log of buggregator when a javascript-app sends an error:

buggregator-1 | {"level":"error","ts":1755854729021872136,"logger":"app","msg":"InvalidArgumentException: Invalid type: session in /app/app/modules/Sentry/Application/DTO/TypeChunk.php at line 17 [] []\n"}

Only the error:

InvalidArgumentException: Invalid type: session in /app/app/modules/Sentry/Application/DTO/TypeChunk.php at line 17

Any idea what could be the problem?
