Expected Behavior

Table gets created as required (and as works fine in 2.4.0).

Actual Behavior

Steps to Reproduce

1. terraform apply -auto-approve

Important Factoids

Running this against the amazon/dynamodb-local container image in a network defined by Docker Compose.

Amplifying this: any endpoint customization blows up under 2.5.0, because we're not initializing the new Endpoints map before using it.

Probably just needs a make(map[string]string) in the Config initialization block?

Hi Folks 👋 Apologies for the unexpected behavior with the last release. I have submitted a fix with a covering test here, which we will release early next week: #8226

The fix for this has been merged and will release with version 2.6.0 of the Terraform AWS Provider later today 👍
