Failed to parse warning

Failed to parse warning:
[{:"{", 1}, {:atom_full, 1, ''ok''}, {:",", 1}, {:"#", 1}, {:"{", 1}, {:atom_full, 1, ''__typename''}, {:":=", 1}, {:<, 1}, {:<, 1}, {:int, 1, 384677985324449735536498}, {:":", 1}, {:int, 1, 80}, {:>, 1}, {:>, 1}, {:",", 1}, {:atom_full, 1, ''error''}, {:":=", 1}, {:<, 1}, {:<, 1}, {:int, 1, 2037172997037120384612}, {:":", 1}, {:int, 1, 72}, {:>, 1}, {:>, 1}, {:"}", 1}, {:"}", 1}]

Legacy warning:
service.ex:0: The pattern {'ok', #{'__typename':=<<384677985324449735536498:80>>, 'error':=<<2037172997037120384612:72>>}} can never match the type {'ok',#{'installment_prices':=[]}}

---

Snippet to reproduce:

    {:ok, %{installment_prices: []}}
    |> case do
      {:ok, %{__typename: "Error", error: "not_found"}} ->
        {:error, :not_found}

      {:ok, %{installment_prices: installment_prices}} ->
        {:ok, Helpers.GraphQLUtils.format_response(installment_prices)}

I think I have another example of this, dialyzer asked me nicely to open an issue but as I think this is a duplicate I'll add it here:

The underlying error was actually a typo in the map field matching against a struct
