R2 migration not showing destination buckets


I’ve got the same issue as this one.

When trying to migrate from an S3 bucket to R2, no destination buckets appear in the dropdown:

I do have a bunch of buckets though, and even created an API token with admin read and write permissions, to no avail.

Can’t find anything that would explain it in the documentation.

Am I missing something?

Anybody else had this issue and managed to solve it? Unfortunately unable to use the migration tool because of this at the moment
