Trying to create a dispatch and just getting “Error [400] - Required parameters are missing: orign, destination”, along with sometimes aircraft as well, regardless of if I’m manually inputting the ICAO code or using the search feature. Editing previous flights also raises this error.
Hi, this is strange.
My initial guess is that a browser extension of some sort is corrupting the Flight Options page, so that some parameters are getting dropped.
Please try disabling any browser extensions (particularly Ad Blockers as they have been known to do things like this).
If that doesn’t work, please try using a different web browser to see if it’s browser-specific perhaps.
Best regards,
Yes, it was initially not working in either Firefox or Edge, but I tried disabling UBlock Origin in both and it works now, so that seems to be the culprit. It’s worked for me for ages now with no issue, so I assume some update must have caused it to block Dispatch from working all of a sudden.
IIRC, when generating Simbrief plan, all the info is transmitted via the URL which becomes quite long. My guess is UBlock Origin mistakes this for “tracking” data and removes some or all of it. You could report it to its developers.

Tim
Out of curiosity, I installed uBlock Origin but couldn’t reproduce the issue here.
Do you recall if you’ve customized any of the uBlock settings?
If you re-enable uBlock does the issue come back? If so, can you try clicking the uBlock icon, then clicking to open the logger window. Let me know what, if any errors appear in the logs when you try to plan a flight.
Cheers,
I did add a couple of filter lists I think? Yes, when I re-enable UBlock Origin, the error reappears. This is what I’m seeing in the logs:

I think it seems to think part of the URL is a yandex related URL, and it’s removing those? That seems to come from a filter list I added that blocks ads on Russian sites, not sure why it’s triggering on Simbrief. I’ve disabled it for now, I’ll have to hunt down the creator to let them know it’s activating accidentally.
Edit: it seems that the filter list was outdated and hadn’t updated automatically, re-importing it seems to have removed the issue.
Interesting, thanks for the follow-up!
Cheers,
