[BUG] Investigate event images upload in the production instance

[sandeep-ps]

Describe the bug

To Reproduce
Steps to reproduce the behavior:

1. Got to Events Manager on production.
2. Create an event with an image.
3. Publish it.
4. Retrieve the image URL from backed and do a GET call.
5. See Http 403 error.

Expected behavior
The image should be associated with the production account, and the image read should work fine.
