The idempotency key search passes jmespath_options (by default the Powertools functions like powertools_json), but the payload validation search didn't pass any options. Any payload_validation_jmespath using powertools_json, powertools_base64, powertools_base64_gzip or a custom function raised "Unknown function" when hashing the payload, so every invocation failed with IdempotencyPersistenceLayerError before the handler ran. Pass the same options to the payload validation search.

Summary
Changes
BasePersistenceLayerpassesjmespath_optionsto the idempotency key search but not to thepayload_validation_jmespathsearch in_get_hashed_payload. By default those options hold the Powertools functions, sopowertools_json(),powertools_base64(),powertools_base64_gzip()and any custom function raisedUnknownFunctionErrorin the validation expression.save_inprogresshashes the payload before it writes the record. So every call failed withIdempotencyPersistenceLayerErrorand the handler never ran._get_hashed_payloadnow passes the samejmespath.Optionsas the key search.powertools_json(body)in both expressions. The same order replays the stored response, and a changed amount raisesIdempotencyValidationError.jmespath_optionsused inpayload_validation_jmespath.User experience
Before:
payload_validation_jmespath="powertools_json(body).amount"fails every call withUnknown function: powertools_json().After: the handler runs, and a repeat request with a changed amount raises
