Problem

After updating to latest vector version I now see an error that wasn't there before:

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

Has there been a change that could cause this in latest version?

Hi @shawaj ! This was a new unused variable warning added in v0.36.0.

@jszwedko so what's the fix here?

Use the err variable or, if you just want to ignore it, use read_at, _ = ... to ignore any errors.
