Curl 404 error downloading lamda.zip artifact

[marlovil]

Describe the Bug

From yesterday, we are getting this error:

Error: failed to execute "curl": curl: (22) The requested URL returned error: 404 

  on .terraform/modules/lambda-elasticsearch-logs-cleanup.artifact/main.tf line 1, in data "external" "curl":
   1: data "external" "curl" {

If we enable TF_LOG=DEBUG we can see this:

returns 404.

We are using 0.12.3 module version. We tried to upgrade to the last recent release (0.12.4) but we are getting the same error.

Steps to Reproduce

Simply run a terraform plan

Environment (please complete the following information):

• Terraform 0.14.10
• Module version 0.12.3 and 0.12.4

Additional Context

This problem started just yesterday. Maybe some thing is broken with the latest release?

[marlovil]

We've found a workaround.

Instead of pinning the module version using:
version = "~> 0.12.3"
We've pinned the exact version:
version = "0.12.3"

Now it works.
