Hi guys, I'm trying to upload my app and I'm facing challenges within the final step getting 400 Unable to process request. Any idea?

I'm on Firefox, Ubuntu.

And on developer.repebble.com it also fails with 400.

You're getting an error for both Rebble and Core Devices?

#

Yes

#

One shows nginx 400 and the other cloudflare 400

#

Huh. The fact that both fail maybe suggests an issue with either the PBW or possibly your internet itself

#

Are you able to try sibmitting from a phone using mobile data?

Sure, will try in the evening

#

Is there a lint or something for pbw validation? It did install successfully on my watch

I don't think so. And either way I don't think it should return a 400 error anyway
