Hi I’m trying to upload my first app to Ionic, to test it with Ionicview but it fails with the error below. Please can you help?

Thank you!


Uh, that’s… interesting.

Did you check if the upload appears on or if it really wasn’t successful?


Hi Sujan, here is what I see at

Seems that it is not completing the upload.
Any clues?


The list looks ok.
Isn’t the 6:14 version the one you uploaded above? Time matches…
Did you try opening the app with Ionic View?

(Ionic Deploy is a different thing, Ionic View only needs to have an entry in “recent activity” with “upload” to work.)


Hi Suman,
I never got a complete upload done. When I try to view it on the Ionic View
I get the attached error:


thank you,


Ok, so the dashboard is lying or not showing all information. Damn.

Do you have something in /www locally? Does ionic serve work?
Try ionic upload --verbose to maybe get more information on the error.


Thank you Sujan!
with the verbose parameter I was able to get more details. It is throwing that cli-plugin-proxy is not installed.


Nah, that is only informational - nothing to worry about if you don’t need to use a proxy.

But this time it times out one step sooner during “Requesting snapshot upload”, not “Uploading snapshot.”.

Are you on a really slow connection somehow?
Can you try again?
Maybe on a faster connection maybe?
