Scap3 doesn't support non us-ascii characters in config templates for service deployments
Closed, ResolvedPublic


When I'm trying to deploy a service where the config.yaml.j2 template contains non us-ascii characters, I'm getting the following error in Scap logs:

Scap should support Unicode in the configs and vars.

For completeness, the deployment fails due to this patch (which is the one containing non-us-ascii chars).

D1077 should have resolved this problem and it is now deployed to production. I'll close this task for now, please reopen if problem persists in production.

Thank you. Just made a deployment and verified it's working correctly with non-ascii configs
