Terraform Archive Error

[niraj06]

Hi

I am getting below error when trying archive and upload google cloud storage.

Failed to read source file "data.archive_file.main.output_path". Cannot compute md5 hash for it.: timestamp=2021-07-07T15:28:12.440Z
2021-07-07T15:28:12.442Z [WARN] Provider "registry.terraform.io/hashicorp/google" produced an invalid plan for google_storage_bucket_object.archive, but we are tolerating it because it is using the legacy plugin SDK.
The following problems may be the cause of any confusing errors from downstream operations:
- .detect_md5hash: planned value cty.StringVal("different hash") for a non-computed attribute

data "archive_file" "main" {
type = "zip"
source_dir = pathexpand("../function/ce-analytics-npd-trainer")
output_path = pathexpand("/tmp/trainer-0.1.zip")
}

resource "google_storage_bucket_object" "archive" {
name = "${data.archive_file.main.output_md5}-${basename(data.archive_file.main.output_path)}"
bucket = google_storage_bucket.cloud_functions.name
source = "data.archive_file.main.output_path"
content_disposition = "attachment"
content_encoding = "gzip"
content_type = "application/zip"
}
