[422] API request client error with Shopify CLI

[Soundsprinkler]

Hi,

I've installed the Shopify CLI, used this command to log in:

shopify theme dev --store {store}

I log in via the browser and I get an answer saying:

✔ Logged in

 But then immediately after I get:

[422] API request client error

That error keeps coming up if I run "shopify theme dev". I've tried logging out and in again with "shopify auth logout", no dice.

If I run:

shopify theme info

It says I'm logged in, and I can push the theme to the store. 

Shopify CLI version: 3.44.1

Anyone know why this is happening and how I can solve it?

@Soundsprinkler  do you still facing the issue?
which version of Shopify CLI client are you using?

Shell          /bin/zsh

Trying to setup a new development store but everytime i tried 'shopify theme dev' command, i have the 422 API Error Message

Hi, any luck on this?  My friend got exactly the same problem.

[Soundsprinkler · Accepted solution]

Solved it by manually uploading the theme via the admin, logging out with the CLI and logging back in again but with the theme ID:

shopify theme dev --store {store} --theme {theme-id}

Thank you so much, we tried your solution and it finally worked!

Your solution made a lot of sense because when we run

shopify theme info

we get

Development Theme ID Not set

which means we should set theme ID with

shopify theme dev

Brand new to shopify cli
Its crazy I was trying to do this, even thought it was staring right at face.

I didnt know how to set theme id.
Finally i did `shopify theme push` to get the theme id

And then I ran command by @Soundsprinkler 
Works now.
