GET sequence: PB downloading

Created by: leapicard

Hello,

I am using Ensembl-rest to download sequences using their CCDS ids. However, for some of them, it is impossible to get the sequences, because the "Content-Type text/html is not supported." The script (very simple & straightforward) works for the vast majority of the sequences, and I can't understand why I run into this problem. Would you have any idea?

Best, Lea
