Cost Estimation Fails with "Something on our end went wrong" Error

Problem

Cost estimation fails with the error “Something on our end went wrong. We’ve been notified. Please try again later.”

Cause

There are several causes to this issue some of which include expired cloud provider credentials or a panic caused by a runtime error.

Solution

To identify the cause of cost estimation failure, use the get run details API endpoint with the ?include=cost_estimate includes parameter. This will return any cost estimation errors that occurred during the run.

1. Gather the run ID.

2. Adjust the following request with the run ID and hostname (for Terraform Cloud, this should be app.terraform.io), then query the endpoint or paste the URL in your browser.

    $ curl \
      --header "Authorization: Bearer $TOKEN" \
      "https://$TFEHOSTNAME/api/v2/runs/$RUNID?include=cost_estimate"

3. Locate the included section and review the cost estimate error message.

   Example:

      "included": [
        {
          "id": "ce-cGoqimyNs2Y8rczy",
          "type": "cost-estimates",
          "attributes": {

            }

4. Resolve any conflicts.

Additional Information

If a panic is returned then submit a support ticket to HashiCorp Support with the run detail output.
