ODC Studio Entity Preview Showing 500 Internal Server Error
Question
ODC


In ODC Studio, data is available in the database entity, but we are unable to preview/view the data in the entity preview.

We are getting the below error while trying to preview the data:

HTTP protocol error. 500 Internal Server Error

Screenshot attached for reference.

Could anyone please help us identify the issue

Regards,
Madhu

Hi @Madhu Krishna Tadi ,

This could be a temporary ODC platform or session issue, not necessarily a problem with the entity itself. Can you try the below points:

  • Try restarting ODC Studio and signing in again.
  • Republishing the app/module is worth trying if recent changes were made.
  • Reviewing logs in the ODC Portal can help identify the actual backend error behind the generic 500 message.

If none of the above option works for you I would recommend to raise a support ticket with OutSystems.
