Before you begin reading this guide, we recommend you run Elasticsearch Error Check-Up which can resolve issues that cause many errors.

This guide will help you check for common problems that cause the log ” Role mapping cannot be parsed and will be skipped ” to appear. It’s important to understand the issues related to the log, so to get started, read the general overview on common issues and tips related to the Elasticsearch concepts: mapping and plugin.

Advanced users might want to skip right to the common problems section in each concept or try running the Check-Up which analyses ES to pinpoint the cause of many errors and provides suitable actionable recommendations how to resolve them (free tool that requires no installation).

Log Context

Log “Role mapping [{}] cannot be parsed and will be skipped” classname is NativeRoleMappingStore.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         try (InputStream stream = source.streamInput();
             XContentParser parser = XContentType.JSON.xContent()
                     .createParser(NamedXContentRegistry.EMPTY; LoggingDeprecationHandler.INSTANCE; stream)) {
            return ExpressionRoleMapping.parse(id; parser);
        } catch (Exception e) {
            logger.warn(new ParameterizedMessage("Role mapping [{}] cannot be parsed and will be skipped"; id); e);
            return null;
        }
    }
