[pmalek]

Is there an existing issue for this?

Current Behavior

When running TestIngressClassRegexToggle in isolation in dbmode=postgres like so:

make test.integration.postgres GOTESTFLAGS="-count 1 -run TestIngressClassRegexToggle"

one can reliably notice the following note from deck

time="2023-02-03T13:45:21+01:00" level=debug msg="converting configuration to deck config" kong_url="http://172.18.1.1:8001/"
1 unsupported routes' paths format with Kong version 3.0
or above were detected. Some of these routes are (not an exhaustive list):

18a19edb-0b01-4d9a-988b-146c3c086e04

Please upgrade your configuration to account for 3.0
breaking changes using the following command:

deck convert --from kong-gateway-2.x --to kong-gateway-3.x

This command performs the following changes:
  - upgrade the `_format_version` value to `3.0`
  - add the `~` prefix to all routes' paths containing a regex-pattern

These changes may not be correct or exhaustive enough.
It is strongly recommended to perform a manual audit
of the updated configuration file before applying
the configuration in production. Incorrect changes will result in
unintended traffic routing by Kong Gateway.
