INVALID_JSON

HTTP 400

Something about the request must change

The request body is not parseable JSON (or a Stripe payload failed to parse).

How to fix it (contract guidance)

Fix the body serialization and retry.

Corrected call

This exact request is exercised by the API test suite. Set PULLBOARD_URL to the deployment origin, then run:

curl --request POST "$PULLBOARD_URL/api/contact" --header "content-type: application/json" --header "origin: $PULLBOARD_URL" --header "x-pullboard-csrf: 1" --data-raw "{\"topic\":\"support\",\"email\":\"error-example@example.test\",\"message\":\"I need help with a documented API error.\",\"requestId\":\"error-reference-invalid-json-1\"}"
Call that triggers INVALID_JSON
curl --request POST "$PULLBOARD_URL/api/contact" --header "content-type: application/json" --header "origin: $PULLBOARD_URL" --header "x-pullboard-csrf: 1" --data-raw "{\"topic\":\"support\""

Observed recovery

Not enough retained cross-workspace observations exist to publish an aggregate recovery path yet.

Publication requires at least 3 distinct workspaces. This is withheld data, not evidence that no recovery happened.
