Summary: RestLookupService not handling HTTP 4xx/5xx error codes Key: NIFI-12875 URL: https://issues.apache.org/jira/browse/NIFI-12875 Project: Apache NiFi Issue Type: Bug Affects Versions: 2.0.0-M2 Reporter: Gregory M. Foreman The RestLookupService service does not handle HTTP error codes correctly. If the web service being consumed returns a 4xx or 5xx error code, the RestLookupService service ignores the error and passes the response content to the record reader, causing unexpected exception reporting. Example: a web service that communicates with clients via JSON is behind a proxy. The proxy returns a 502 error and responds with HTML content describing the error. The RestLookupService uses a JsonTreeReader reader and attempts to parse the HTML characters. This leads to it throwing an exception that it was unable to parse the '<' character. The real reason is the proxy is sending back a 502 error, but this detail is hidden. -- This message was sent by Atlassian Jira (v8.20.10#820010)
