External Object Connection is returning 500 Server error
Answer ID 13043 |
Last Review Date 08/29/2025
Environment:
External Objects (XO)
Oracle B2C Service
Issue:
We have created an External Object (XO) connection on our site but it is failing with 500 Server Error. When I checked with the developer of API they confirmed that they have not received any hit for the API.
The same API is working from Postman and even from Plugin code present on the page but not from the External Object connection. Can you please tell me reasons this might occur, and how to fix it?
Resolution:
XO is only able to connect to endpoints available across the public internet, and the described behavior (500 error) is expected when requests are made to resources behind a corporate firewall, for example. Testing the same connection directly (not using the XO feature) from different network locations can potentially rule this out as the cause. Otherwise, if the endpoint is available from the public Internet and works fine in unit tests outside of the XO feature, it may be prudent to submit an SR to Support for assistance.
