Hi folks. I am using the CDS Configuration Migration tool to transfer Dataverse records between environments. I've used this tool in the past with great success.
This time, I'm trying to migrate data from Dev to UAT. I'm able to create a schema from Dev and export the data without issue. This is where things start to get weird.
On the Import step, I'm able to log into and access any environment except for UAT (I have access to 7 environments). I've selected every single other environment and I authenticate and am given the option to start the import. With the UAT environment (which my account has full access to and is a System Administrator in), the application kicks me back to the login screen. No error, no logs generated, nothing. This behavor occurs no matter which step I choose - Create schema, Export data, and Import data all fail when trying to access this UAT environment.
I reinstalled CMT and the behavior persists.
This is odd, because I've imported data into UAT before without issue. Does anyone have any ideas?
