Hey folks!
I’ve got a branch in Absinthe that conditionally uses the :persisten_term module if it’s available. Unfortunately this is causing me issues with dialyzer, for reasons I can’t quite sort out. I’d like to do one of two things:
- Figure out why dialyzer things
:persistent_term.put/2is unavailable on OTP 21.2. This would be the best option. - If that fails, mark the function as
nowarn. I’ve tried this, but I can’t seem to get the invocation correct.

Sometime in the past, for reasons I don’t recall (but I think i was heading down the same path as you) I added the following to my
.dialyzer_ignore_warningsfie which seemed to quiet things down. Hope it helps make some progress.I think this may also have been because of the
@dialyzerissue you are having - i think I had the same but can’t fully recall.benwilson512

I’d still like to sort out why dialyzer doesn’t think persistent_term.put exists for that version of Erlang though.

We’ve now hit this issue in OpenTelemetry Fix dialyzer issues by davydog187 · Pull Request #82 · open-telemetry/opentelemetry-erlang-api · GitHub
But what is extra weird is that dialyzer has been working fine, no warnings about
persistent_term:put/2. It is only now that Elixir’s dialyxer task has been added that its use of dialyzer warns about the function…
