Curl 404 error downloading lamda.zip artifact

## 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?
