Runtime error: invalid memory address or nil pointer dereference

[Kerem Bozdas]

I get the following error when I try to run go run main.go (same with prebuilt binary).

panic: runtime error: invalid memory address or nil pointer dereference                          •

Hi @krmbzds

Thanks for letting me know about this. Right now this is a bit difficult for me to debug since it is not something I can reproduce on my machine. I will try and see if I can find something out based on the panic.

Had the same bug when starting circumflex in zsh. Worked fine in bash

@jspruyt Thanks for letting me know! I created a terminal profile with /bin/bash as login shell to test this out. No luck. I still get the same error message.

It looks like an issue with fetching the initial submission lists.

Are you able to manually fetch results from the endpoints in your browsers?

Submission list: https://hacker-news.firebaseio.com/v0/topstories.json

Details for each item: https://hn.algolia.com/api/v1/search?tags=story,(story_33281106,story_33281682,story_33278698,story_33283674,story_33258410,story_33283712,story_33276342,story_33275935,story_33276601,story_33281310,story_33284659,story_33281148,story_33279036,story_33282883,story_33263567,story_33268199,story_33279290,story_33275418,story_33277865,)&hitsPerPage=19

For 2.7 I am planning to add an option for logging to make troubleshooting easier, as well as better error messages.

Hey, that's it! I had to whitelist hn.algolia.com in my firewall and now it works. Thank you!

Glad it works! Thanks again for submitting the ticket, it is helpful for me to know so I can create more useful error messages in the future.
