Can't open .igv files from pre-signed S3 links

[alex-seitz]

Hello,
I'm trying to set up a predefined igv session. There I use pre-signed S3 links.
It works great with vcf, bam, and bed files, but It doesn't want to open *.igv files. It always terminates with an "Unknown filetype:"

Errors were encountered loading the session:
https://...NA12878_29_bafs.igv?X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=A4QV58EQ906C3FQDZ8KC%2F20210302%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20210302T124036Z&X-Amz-SignedHeaders=host&X-Amz-Expires=28800&X-Amz-Signature=62edd75ee09c0aebc17da88fa83ec9cd2345dea23e746273f19e8fa6cd4a783b 
org.broad.igv.exceptions.DataLoadException: Failed to parse line 0: Unknown file type:

My session entry looks like this:
<Resource path="<link from above>" />
Is it possible to add the dataformat to the resource tag?

I read somewhere, that it might be possible to set the dataformat=.igv to the link, but this breaks the authorization.
Is it possible to add the dataformat information to the Resource tag somehow?

The file works fine, when I download it and open it from local storage. There it also works from a saved session file.

Tested on IGV version 2.9.2

Best,
Alex

@alex-seitz I will look into it. That should work as is, the extension of the path (before the parameters) is. ".igv".

@jrobinso thank you.
I realized that the same problem exists with opening .igv-files through the "link API" meaning the http://localhost:60151/load?file=....igv...

Maybe this helps with the diagnostic.

Best,
Alex
