Cors issue upgraded parse-server from 3.4.4 to 3.5.0

Hi guys.

One of my parse-server needs to upgrade from v2.5 to v3.8 in order to use apple sign in.
I am able to upgrade to v3.0 using this guide
But I can only upgrade up to v3.4.4, beyond this Cors issue will happen.

Any idea?

Could you give more details about the cors issue that you have?

Thanks for reply.

After further investigation, seems that the application has some errors while running.
