cfdyndns fails when a `CAA` record (or any other unknown RR type) exists in the zone about cfdyndns HOT 4 CLOSED

@fadenb I've submitted a PR to fix this issue, but until it has been accepted you can apply the patch manually as such:
diogotcorreia/dotfiles@431e8bc

Let me know if it works for you :)

@diogotcorreia the patch works perfectly. Thank you :)

I've literally just encountered this problem myself (after my IP changed and the DNS did not update; I found that the cfdyndns service had failed).

After some digging, it seems like it's a problem in the cloudflare crate (of which I could not find any GitHub link of): https://docs.rs/crate/cloudflare/latest/source/src/endpoints/dns.rs
The enum DnsContent does not have a CAA record, which causes the parsing of the API response to fail.
I'm really not sure how to fix it, I think we are dependent on upstream fixing the issue (not sure how to report it either; I could not find an issue tracker).

Upon some further inspection, I think it should be possible to go around this problem by adding some parameters to the fetch request:

Feel free to make a PR fixing this if you can, otherwise I should be able to submit one a few days from now.
