ansible 2.8: "skip: true" vs "errors=ignore"

[philfry]

SUMMARY

find_first: with ansible 2.8 skip=false is marked as deprecated in favour of errors="ignore".
But when using errors="ignore" ansible tells me to use skip: true instead and fails.

Looks like my syntax is wrong. It should be

loop: '{{q("first_found", dict(files=["a.yml", "b.yml", "c.yml"]), errors="ignore")}}'

instead of

loop: '{{q("first_found", dict(files=["a.yml", "b.yml", "c.yml"], errors="ignore"))}}'

It still doesn't work but that's a different issue.
Closed in favor of #56775

+1. Affected by the same issue.

[andrewrothstein]

me three. I use with_first_found heavily.

[geerlingguy]

I'm having this same issue. Not sure why this issue was closed, but I opened up a bug ticket #58942 because the documentation should be fixed to not recommend a solution that's deprecated (and ideally, that non-deprecated usage would also... work?)
