Using the Tinybird web analytics tracker (flock.js) in a Next.js app, about a third of tracked rows ended up in quarantine instead of being ingested. The quarantine error was Strict type checking failed. Object does not have column 'session_id', you should send a value or recreate the table with a Nullable column type. While accessing jsonpath '$.session_id'. The reporter had 340 good rows and 150 quarantined.
