Error codes

validation.parameter_invalid

A query or path parameter failed bean-validation rules.

validation.parameter_invalid is returned at HTTP 400.

When this fires

Spring's ConstraintViolationException on a @Validated controller. Common cases: a limit query parameter outside its @Min/@Max range, a malformed cursor, or an id path segment that is not a ULID.

What to do

Read errors[] for the failing parameter name and rule. The SDKs validate most of these client-side; a 400 here usually means a hand-rolled HTTP call.
