I reverted today's deployment of envvars-api 0.0.50 because that depends on envvars-cli commit 3c116128 which hasn't been deployed yet. This was manifesting as "Error: method not allowed" errors when creating new envvars.
Please either immediately deploy the envvars-cli changes and then roll envvars-api forward again, or revert the breaking change to envvars-api and then deploy that revert.
