se criar o bucket com mesmo nome do professor pode dar erro se este bucket ainda existir. O erro é o seguinte:
rror: Error creating S3 bucket: AuthorizationHeaderMalformed: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'sa-east-1' status code: 400, request id: 84AF46B9F8BB5793, host id: 5j60AgyQyRN16btNLPU8cCig2KM81Lp5oX1pR/ocTcDAvUru1ycRgPHG0qLYCri0fvnM8S47y8U=
on main.tf line 68, in resource "aws_s3_bucket" "dev4": 68: resource "aws_s3_bucket" "dev4" {
Se acontecer, troque o nome do bucket .
