Constant 503 errors from resources

Same issue here and others are getting it on this ticket.

Same problem on brand new project. I have reported it as you suggested.

Here’s a full error output if it helps :slight_smile:

Not really as this is the default Heroku error message - but the only people that could do anything about it are the Ionic team which you can only reach by using the support route - they are not very active here in the forum.

Ah no problem I’ll go submit a bug report :slight_smile:

I have same problem!

It was back for me for a moment there…

and the CLI looked like it was working again, but looks like it’s fell over again :frowning:

Awww boooo!! Hoping some wizard at Ionic fixes it soon, sat here being unable to work :frowning:


The whole concept of using a webservice to resize your resource images is reasonably sound in terms of keeping the service up to date… but surely it’s more sustainable (for ionic the company ) to use some kind of npm local app to do it?

Starting to feel a little uncertain about their cloud provision stuff in the light of the ionic push rug being pulled from under people’s feet… and now basic infrastructure going wobbly :frowning:

Working perfectly now :+1:


i have the same problem now

I have to run “ionic cordova resources ios” 4 times.
Don’t know why.
Generating platform resources: 8 / 32 complete - failed!
Generating platform resources: 12 / 32 complete - failed!
Generating platform resources: 17 / 32 complete - failed!
:heavy_check_mark: Generating platform resources: 32 / 32 complete - done!

Use steps from support page:

npm uninstall -g ionic
npm install -g @ionic/cli
npm install -g cordova-res
ionic cordova resources

Sir can you tell me how to fix above error I have got same error?

Are u fixed above issue after install above plugin?

Yes, use cordova-res, ionic doesn’t use the server based resource service anymore…


Sir I have fixed above issue via below command.
npm i -g ionic@latest

Worked for me.
Thank you

Thanks!! worked for me too :grinning:

You forgot to uninstall ionic first

npm uninstall -g ionic
npm i -g @ionic/cli

It helped to fix.

The main issue is old ionic cli 3 version send images to cloud.
New Ionic cli 6 version convert images locally
