[Bug] Wingbits: Warning message in the logs

[ketilmo]

Over the last few weeks, a warning message has appeared in the Wingbits service logs. This is likely due to changes in the Vector service, as it appears on both new and old versions of the Wingbits feeder configuration.

This is the warning message:

WARN transform{component_kind="transform" component_id=remapped component_type=remap}: vector::transforms::remap: VRL compilation warning. warnings=
warning[E900]: unused variable `err`
ââ :1:10
â
1 â read_at, err = .now * 1000
â          ^^^ help: use the result of this expression or remove it
â
= this expression has no side-effects
= see language documentation at https://vrl.dev
= try your code in the VRL REPL, learn more at https://vrl.dev/examples

The feeding seems to work correctly.

@shawaj Would you be able to take a look at this? Also, it would be great if you could confirm that the recent updates to Wingbits have been correctly reflected in recent changes to the balena edition.

[shawaj]

@ketilmo sure I'll take a look.

When you say the vector service, you mean it's been updated to a new version in later images?

[ketilmo]

Thanks @shawaj! And correct. When I rolled back to an earlier deployment, the warning message disappeared. So it's likely been introduced by a recent Vector service update (via apt).

Same issue as mentioned here https://gitlab.com/wingbits/config/-/merge_requests/22

[shawaj]

Pulling in latest update (i.e. clicking on deploy with balena) should fix this now.

[shawaj]

Actually probably need to bump version. I will sort a PR shortly

[ketilmo]

Thanks @shawaj, much apprecaited!

[shawaj]

Looks like they are no longer tagging the release upstream, so latest config update is 0.0.5 but there is no tag.

@ketilmo are you happy if I just remove the tag based build and use a commit hash instead?

For example https://gitlab.com/wingbits/config/-/blob/96cb3ffb4628fbb8a128a02d691ee16bdff7f917/vector.yaml

[ketilmo]

That sounds like a good approach, @shawaj! Please go ahead.
