I have a solution with a custom API that fails when importing into a fresh on-prem v9.1 org. It will import to 90 percent then fail with a generic error: “The operation timed out. This may be because a solution is currently being imported into this environment. Please try again after the solution import is completed. Solutions should be imported outside of working hours if possible.”
I’ve tried updating the time out, which did nothing as I get the same error. After removing the custom API folder from the solution, it imports successfully.
Anyone have success importing a custom solution containing a custom API on a fresh on-prem v9.1 org?
As a side note, I also tested having a basic “Hello World” custom API solution, which also fails.
Thank you
