Vector sink for http endpoint doesn't except ENV variable for uri

[JustinJKelly]

Question

The value for uri is giving me an issue, presumably due to requiring a string value. When I hardcoded a string it worked with keeping token: ${DEV_TOKEN} the same. Seems to only be an issue with uri.

Error:
ERROR vector::cli: Configuration error. error=invalid format in sinks.sink_main.

Is there any workaround for this? Is this expected behavior or should I open a bug?
Thanks.

Vector Config

    sink_main:
      uri: ${DEV_URI}
      type: http
      encoding:
        codec: json
      auth:
        strategy: bearer
        token: ${DEV_TOKEN}
      inputs:
        - logs_remap

Hi @JustinJKelly,

I cannot reproduce this locally.
