DXA app is intermittently able to retrieve content -- sometimes it works and sometimes the DXA app throws a 500 error with below exception.

ERROR SqlExceptionHelper - ORA-00904: "BINARYVARI0_"."NAMESPACE_ID": invalid identifier ERROR ODataFunctionProcessorImpl - Unexpected exception when executing a function. javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not extract ResultSet

This may be a known issue and possibly an upgrade to DXA 2.0 should resolve this intermittent 500 error.

I would recommend getting in touch with the SDL support and get their opinion about it.

background: In one of our project we were receiving quite intermittent 500 Error and it was because of older version of newtonsoft json dll in DXA - and recommendation was to either update the version of that specific dll or upgrade to DXA 2.0

  • It would highly surprise me if the mentioned DB error could be caused by the version of Newtonsoft JSON used by the Web App. Nevertheless, contacting SDL Support sounds like a good advice. – Rick Pannekoek Apr 18 at 17:28

    Thank you all for the response. The issue was happening due to some bad storage info in the cd_storage file of the content service. When updated it resolved the issue. – user2869 Apr 22 at 13:32
  • glad it is resolved! – Pankaj Gaur Apr 25 at 7:39
