Npm run dev failed with javy error

[IUsedToLift]

After creating a new remix project, I generated extension with template "product_discounts".

Then, after running npm run dev, I got an error:

Error: Command failed with exit code 3221225781: npm exec -- javy --version

I'm using shopify version 3.50.1 I also installed javy globally.

Any additional detail on the javy failure if you run the following?

npm run dev -- --verbose

[IUsedToLift]

Not exactly. Requests to the Partners accounts and

    Error: Command failed with exit code 3221225781: npm exec -- javy --version
── external error ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Error coming from `npm exec -- javy --version`

Command failed with exit code 3221225781: npm exec -- javy --version

If I switch to shopify version 3.48.4, as in a function example on github, I now get

── external error ────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────

Error coming from `npm exec -- javy compile -d -o C:/path-to-the-project/extensions/product-discount/dist/function.wasm dist/function.js --wit
C:/path-to-the-temp/Temp/xxx/javy-world.wit -n shopify-function`

Command failed with exit code 3221225781: npm exec -- javy compile -d -o C:/path-to-the-project/extensions/product-discount/dist/function.wasm dist/function.js --wit
C:/path-to-the-temp/Temp/xxx/javy-world.wit -n shopify-function

When i run

 npm exec -- javy compile -d -o

in the command line myself, it fails with exit code 1 without any further logs

Can you try deleting any javy binaries in the following path, and then try again?

C:\Users\<user>\AppData\Local\binarycache\

If that doesn't solve, can you try running the javy binary directly from this path, after it's downloaded again?

[IUsedToLift]

Deleting binarycache didn't help.

I'm sorry but I don't know how to run the javy binary?

[IUsedToLift · Accepted solution]

OK this is what I end up doing:

1. Download binary from Javy repo 
2. Put it in the binarycache folder- mind that javy-v1.2.0 is a file, renaming from .exe is required

C:\Users\<user>\AppData\Local\binarycache\Cache\javy-v1.2.0
