Problem

Login to Admin Node Manager UI (8090) is failing after updating API Gateway. The failed login is logged in Node Manager trace like below:

ERROR 27/Oct/2022:10:40:39.544 [31177d:07445a631a00328f1fc443a1] java exception: java.lang.NoSuchFieldError: ApiManagementAllowRateLimit

Resolution

The solution is to remove any previous patches from your INSTALL_DIR/apigateway/ext/lib and INSTALL_DIR/apigateway/META-INF directories (or the ext/lib directory in an API Gateway instance).

All patches have already been included in API Gateway One Version, so you do not need to copy patches from a previous version.
