Problem/Motivation

Any attempt to set an envvar in the addon config fails silently (while other config entries can be modified successfully). E.g.:

{ "auth": true, "reporting": true, "ssl": true, "certfile": "fullchain.pem", "keyfile": "privkey.pem", "envvars": [ { "name": "INFLUXDB_DATA_CACHE_MAX_MEMORY_SIZE", "value": "512m" } ], "log_level": "debug" }

Expected behavior

New envvars section accepted as valid config.

Actual behavior

Config panel is not refreshed but, leaving and re-entering addon management page shows that config remains unmodified.

Steps to reproduce
