## The problem
Issue Qovery/terraform-provider-qovery#152 (closed, 6 comments): ``` resource "qovery_container" "some-container" { environment_variables = [ { key [your value] value = "" }, ] } ``` Will result in: ``` ╷ │ Error: Error on container create line 417 │ │ with qovery_container.registry-cache-container, │ on qovery.tf line 109, in resource "qovery_container" "registry-cache-container": │ 109: resource "qovery_container" "registry-cache-container" { │ │ failed to create container: invalid container upsert request: invalid variable diff request: invalid │ variable upsert request: Key: 'UpsertRequest.
## What to do
[spacedub (reporter)]: Workaround: Qovery rejects empty-string env values on container create. Use variable interpolation with a non-existent variable to get an empty string anyway, e.g. TLS={{CHEAT}}.
