[Bug]: When creating an aws elastiCache user, the user id in the camel case naming method was all lowercase, which further caused the problem of user group reference failure.

[Rico00121]

Terraform Core Version

1.5.6

AWS Provider Version

5.46.0

Affected Resource(s)

aws_elasticache_user aws_elasticache_user_group

Expected Behavior

create aws_elasticache_user and aws_elasticache_user_group successfully

Actual Behavior

Terraform helped me create a user whose user_id is all lowercase, but I declared the user_id named in camel case.

The same problem occurred when creating the aws_elasticache_user_group .

Important Factoids

user_id = "testUserId" -> On AWS, a user with user id “testuserid” will actually be created. user_group_id = "userGroupId" -> On AWS, a user with user group id “usergroupid” will actually be created.
