Module does not support for_each due to hard coded providers

[heathsnow]

Describe the Bug

The module is unable to support for_each since it contains provider configuration:

Module "foo" cannot be used with for_each because it contains a
nested provider configuration for "aws.requester", at
.terraform/modules/foo/requester.tf:60,10-15.

Expected Behavior

The module should support for_each loops.

Additional Context

I believe passing the providers into the module (instead of configuring the providers w/in the module) would do the trick. I labeled this as bug but it may be a feature request instead.

Hi all, any update in this feature?

I think this would be a good extension to this module. Since this would be a breaking change, we'd require a migration doc, updated examples, and move to the next major version of 1.x. We would also try to close as many open issues as possible with prs for that release.

I'd like to work on this when I find the time. Feel free to contribute the change too and we will review.
