Loading Annotation Track From S3, incorrect gzip header check

[jasongallant]

Hi @cmdcolin and team-- I'm trying to revamp our genome browser using react, hosted on S3. I've got a valid gff3 that has been sorted and tabixed, but when trying to load in the browser, I'm getting this issue. Any ideas about how to go about diagnosing/fixing?

Let me know if there is more info I can provide.

Cheers,
Jason

Should add that the reference sequence loads fine, which is compressed and indexed.

Adding more helpful error in browser inspector, with the hopes this helps :)

Doh! This was a coding issue.

[cmdcolin]

was it related to Content-Encoding:gzip headers by chance? this is something that i have often seen with these errors!

[jasongallant]

Lol nope— bad coding on my part was pointing to a nonexistent uri! I went down the encoding rabbit hole for an hour before I realized it!

interesting! i wonder why it didn't give the proper http error in that case, but glad you found the fix :)
