I am working with a client who is having their instance migrated to another pod. As part of our preparations, we want to test how integrations will behave when the org goes into read-only mode.
As a first step, we asked Salesforce support to enable read-only test mode in a couple of our sandboxes. Unfortunately, when trying to enable read-only mode in a sandbox we get a "Feature is currently unavailable at this time. Please try again later." which is not helpful at all. Salesforce support is looking into it, but not expecting anything useful back.
If others have had issues testing read-only mode in a sandbox or even better got a similar error message when trying to enable read-only mode in a sandbox then I would love to hear from you.
However, my main question is that based on the read-only mode overview article we can expect the following error code returned from the Salesforce API
I wanted to know if the HTTP Response Code would be 500 in this instance? It is not 100% clear based on both the article above and status codes and error responses guide
I know there is a similar question already but that did not get any traction, hence asking again.
