Hi,

I have a Lambda module that uploads a ZIP file to S3 using aws_s3_bucket_object function.
This works fine for my project until today when i'm using small ZIP files under 1KB.
I had this error when i tried to execute my code:

> Error: Error putting object in S3 bucket (): InvalidParameter: 1 validation error(s) found.- minimum field size of 1, PutObjectInput.Bucket.

As far as i now the minimum size of an object PUT in S3 is 0KB, so why Terraform is not able to upload the ZIP ?

Terraform Version

0.12.3

Terraform Configuration Files

resource "aws_s3_bucket_object" "object" {
  bucket = "${var.s3_bucket_sources}"
  key    = "lambda/${var.function_name}/lambda.zip"
  source = "${path.module}/sources/${var.source_code}"

  # Used to trigger updates when source code changes
  etag = "${filemd5("${path.module}/sources/${var.source_code}")}"

}

Debug Output

Error: Error putting object in S3 bucket (): InvalidParameter: 1 validation error(s) found.

• minimum field size of 1, PutObjectInput.Bucket.

Actual Behavior

It looks like Terraform is not able to upload files with size less that 1 KB

Please delete this ticket, it was a problem with the name of the Bucket because it was empty. So it's not related to file size.
Thanks.

Hi @hdryx 👋 Thank you for reporting this and for following up here with the extra details. It seems like we might want to introduce plan time validation for that parameter so at least it ensures that a non-empty string is provided.

For anyone interested in implementing it, adding ValidateFunc: validation.NoZeroValues on the bucket and key attributes in the aws_s3_bucket_object would resolve this. 👍

The validation for this has been merged and will release with version 2.23.0 of the Terraform AWS Provider, in the next day or two. Thanks to @vedsmand for the implementation. 👍
