Error in `qualtrics_response_codes()` for fetch_distributions() & 0 observations for all_mailinglists()

Dear developers,

I ran into these two issues while running the package, and my API worked well to fetch the survey.

I got 0 observations for all_mailinglists(). No error message.

For fetch-distributions():

> distributions <- fetch_distributions(surveys$id[1])
