Hi @kip thanks for the suggestion. I added a file with those lines to that file and at first it didn’t work, but then switched it to using the Elixir formatted documented by dialyxir. This worked!
Commit: Persistent Term Backend by benwilson512 · Pull Request #895 · absinthe-graphql/absinthe · GitHub
Dialyxir format: GitHub - jeremyjh/dialyxir: Mix tasks to simplify use of Dialyzer in Elixir projects. · GitHub
I’d still like to sort out why dialyzer doesn’t think persistent_term.put exists for that version of Erlang though.
