Invalid JSON
Canonical type:
https://learn.peios.org/wispist/problems/invalid-json/
Status: 400 Bad Request. Browser code: invalid_json.
The submitted document representation is not permitted JSON. Wispist rejects malformed or invalid UTF-8 input, a data root that is not an object, duplicate object member names, more than 32 nesting levels, keys longer than 256 UTF-8 bytes, and trailing JSON values.
Generate the body with a normal JSON serialiser and pass a non-null object to the browser client. Duplicate members must be fixed at the producer; Wispist does not choose which ambiguous value wins.
An oversized representation uses Request too large instead.
