Impossible to create a new Custom App on Partners platform

[CosoDev]

Hello,

I'm trying to create a new Custom App on Partners platform following the instruction below:

https://shopify.dev/tutorials/authenticate-a-custom-app-with-oauth#create-a-custom-app-and-generate-...

As shown on the screenshot, I've selected a Custom App and filled in all the fields required. Once I click "Create app" button, the error pops up:

Something has gone wrong and your app could not be created

Thanks for any help!

Hey, @CosoDev!

Welcome to Shopify Community. My name is Olivia and I work here.

Thank you so much for reaching out to our community with your issue. I tried to replicate the error on my end, but I wasn't able to. Furthermore, I don't see any downtime or page failures that could have interrupted your app creation to cause this error.

Help me narrow this down further by ruling out local errors with some simple troubleshooting:

• Try clearing cache/cookies of current browser
• Try from a different, up-to-date, browser
• Try from a different network connection

Let me know if the issue persists after that, and we will have some more context to work with. If it does persist, go ahead and grab any time stamps, screenshots and a copy of the page elements through Chrome DevTools (via Google Chrome > right click on page error > inspect).

I look forward to hearing back.

Warm regards,

Hi Olivia!

Thank you for your effort.

Unfortunately, simple troubleshooting provided didn't help:

• Try clearing cache/cookies of current browser - did it on Chrome latest ver
• Try from a different, up-to-date, browser - tried on Edge
• Try from a different network connection - this time I switched to Vodafone mobile network operator (via iPhone's hotspot)

Here are the error details from Chrome DevTools, right after Create app button clicked:

Thanks for the quick reply, @CosoDev.

This information is great. I will work with our Partner team to troubleshoot this further with you. I will need to authenticate your account in order to look at your development store's logs, so we will move this conversation over to email.

Please keep an eye on your inbox and reply to me there.

Warm regards,

[CosoDev]

Thanks @Olivia ! I just replied over the email.
