Hello @abnv418,
I seem to be able to load qlog files from disk without issue on https://qvis.quictools.info, so I'm not sure what's going wrong...
Could you maybe attach an example file that doesn't work for your here?
Additionally, could you open up the browser Developer Tools in Chrome and check if there are any red errors in the JavaScript console?
Could you also test option 3 (load pre-made demo files) and see if that works?
Normally, when uploading files to qvis, nothing is actually "uploaded" to the server, so the files are just loaded in your local browser, so it shouldn't be a server-side problem either.
With best regards,

Hi @rmarx,
Thanks a lot for your reply. I'm attaching a zip file which contains the qlog file and the console error shown. I tried the option 3, It does work. Still the uploaded file is not working.
Please advise what seems to go wrong.
Thanks
Best,

Hey @abnv418,
The problem seems to be that this file is a newer qlog format (called "draft-02"), but inside the file itself, it claims to be an older format "draft-01" (see the "qlog_version" field at the front of the file). As such, qvis tries to interpret it as the older version, failing to find some fields that were needed then, and failing.
Simply changing the version to "qlog_version": "draft-02"
in the qlog works and I can load the file.
It still gives a warning about a missing field that's mandatory in "draft-02", but using the default for that is fine in this case.
I am wondering how you generated this file though... it says the client was aioquic, but AFAIK the current aioquic builds don't have this type of problem. Are you using a custom version or should we create an issue at aioquic as well to fix this?
With best regards,

Hi @rmarx ,
Thanks for your prompt reply. I'm using a custom version of aioquic. There is nothing wrong in aioquic.
I also checked from my side after changing the draft-02 in the qlog file it shows a message of non compliant qlog-draft. Is this the same warning which you also get ? Attaching the screen shot for your reference.
Just wanted to confirm with you that this pop up does not impact the visualization in any way ? Is there any way I can generate the draft-1 qlog file or do something to remove this warning .
Please guide.
Thanks.

Hey @abnv418,
good to hear there's nothing wrong with aioquic :)
That is indeed the warning that I get as well, which can be easily solved by adding the "qlog_format": "JSON"
field at the same level as the "qlog_version" field (e.g., right before/after it). See an example here: https://quicwg.org/qlog/draft-ietf-quic-qlog-main-schema-01/draft-ietf-quic-qlog-main-schema.html#name-the-high-level-qlog-schema. That should make the file (more) draft-02 compliant.
"JSON" is the default value for that field, so it just works, but qvis shows the warning to try and force people to make more compliant qlogs for more recent versions :)
