The Search landing page displays error messages when the system encounters issues with data indexing. You can find solutions to these issues by analyzing the corresponding error messages.

The system indicates issues with indexing of specific classes by displaying a warning icon in the Status column. You can view detailed descriptions of the issues by clicking the icon.

The following table presents the error types that you can encounter during data indexing:

Error types

Category System message Possible reason
Connection Connectivity problems to the service or network issues, try to reindex again, or contact the support if the problem persists.
  • Socket errors, such as a broken pipe.
  • Invalid URL to the service.
  • Network issues.
Authentication Authentication failed while connecting to the service, try to reindex again, or contact the support if the problem persists. Search and Reporting Service (SRS) does not accept the JSON Web Token (JWT) that Pega Platform provides.
Database Failed to read instance data from Pega database, please contact support.
  • Failed database connection.
  • Invalid database table definition.
  • Other problems with reading the instance from the database.
Storage The service reported a problem while indexing the data, please collect the logs and contact the support. SRS encounters issues while indexing data. You can view the details in broken queue items. This type of issue requires an investigation by the SRS team.
Indexed data Some instances could not be indexed: instance too large, or data not indexable. Consider excluding problematic classes or properties from Relevant Records and/or Custom Search Properties and reindex again.
  • The indexing request exceeds 10 MB, which due to network limitations is the maximum allowed request size.
  • SRS rejects data because of an invalid file format, or a bug in the customer application (for example, empty values for key properties).
Classdef Bad class definition detected: incorrectly imported application or corrupted database structure. Please fix the issues and try to reindex again. The indexer cannot read class definitions from the database, and so data indexing is not possible. The root cause is outside of the indexer.
Data model Data model mismatch detected. Check if the most recent data model is published and try to reindex again. Indicates conflicts between the existing property mappings and newly indexed data. This error triggers the PEGA0124 alert.
You can view a more detailed description of the issue in the Data model section on the Search landing page.
Internal Unknown indexer issue, please collect the logs and contact the support. Includes exceptions that do not match any other category.
