Shopify app deploy fails with INTERNAL_SERVER_ERROR during app version creation

Alex_Law · October 29, 2025, 9:04am

I have reproduced the issue on the latest CLI version.

Yes, I am on the latest version

I have searched existing posts and this report is not a duplicate.

Yes, this isn’t a duplicate

In which of these areas are you experiencing a problem?

Function

Expected behavior

When running shopify app deploy --force, the deployment should complete successfully after:

Building all extensions (Rust functions + UI extensions)
Validating WASM files
Uploading assets
Creating/releasing the new app version

The app version should be created and available for use in the dev store.

Actual behavior

he deployment fails consistently during the “Releasing/Creating an app version” stage with an INTERNAL_SERVER_ERROR from the App Management GraphQL API.

All previous stages complete successfully:
I can Building extensions
Validating WASM files - OK
Uploading assets - OK
Creating/Releasing app version (fails here with error code: INTERNAL_SERVER_ERROR) - Fail

The error has occurred consistently across 4+ deployment attempts over 2+ hours, suggesting a backend API issue rather than a transient problem.

App Client ID: ed7070ba7814007b632b78c488b67a49

Reproduction steps

Create a Shopify app with the following structure:
- 2 Rust function extensions (type: product_discounts, targeting wasm32-wasip1)
- 1 UI extension (admin discount settings)
Ensure all extensions build and validate successfully locally
Run: shopify app deploy --force
Observe that build, validation, and upload stages complete successfully
Deployment fails during “Releasing an app version” with INTERNAL_SERVER_ERROR

Note: Issue also occurs with shopify app deploy --no-release --force

Hey @Alex_Law - thanks for sharing all of this info. I was able to pull some internal logs with the request IDs you shared, looking into this now. I’ll loop back with you once I have more info to share.

Alan_G · October 30, 2025, 8:07pm

Hey @Alex_Law - would you be open to sharing your app.toml and extension toml files? I was able to work with some folks and we’re wondering if the issue is related to config. Let me know if you’d rather share those over a DM privately and I can set one up - hope to speak soon!

Alan_G · November 3, 2025, 9:13pm

Hey @Alex_Law - just looping back on this. I was able to do a bit more digging and can confirm that this happens when there’s a corrupt target value in [[extensions.targeting]] (doc reference here).

We are working on a fix for this (can’t guarantee the turnaround time), but did just want to confirm this is on our radar. Passing a valid value should work though. Let me know if we can assist further on this.

I also have this issue

[
{
“message”: “Internal error. Looks like something went wrong on our end.”,
“extensions”: {
“code”: “INTERNAL_SERVER_ERROR”
}
}
]

Request ID: 1ca045e6-cbde-47a6-893f-90e23b4f544d-1762553782

I’m not sure how to proceed as i don’t have visibility of the issue

Alan_G · November 10, 2025, 7:30pm

Hey @Peter_B thanks for sharing your request ID there. Taking a look at our logs, I think this may be a similar issue related to extension values being passed in the extension toml file (or however you declare extension config if you’re not using our template). Would you be open to sharing your extension.toml config (just sharing for context) so we can take a look? If it’s easier to share over DM, let me know and I’d be happy to help that way. Hope to hear from you soon!

Hello Alan,

I am very sorry, I just saw this message.

Thanks for the investigation. I change the project using rust and not issue at all.

I can deploy to dev platform now.

This is the new extension.toml. I deleted the old one

api_version = “2025-01”

[[extensions]]
name = “t:name”
handle = “variant-promo-discount”
type = “function”
uid = “2f101a71-df63-2e6b-e6c2-3736c864fb530d3145aa”
description = “t:description”

[[extensions.targeting]]
target = “purchase.product-discount.run”
input_query = “src/run.graphql”
export = “run”

[extensions.build]
command = “cargo build --target=wasm32-unknown-unknown --release”
path = “target/wasm32-unknown-unknown/release/variant-promo-discount.wasm”
watch = [ “src/**/*.rs” ]

[extensions.ui]
enable = true
paths.create = “/app/discount/new”
paths.details = “/app/discount/:functionId/:id”

Thank you

Kind Regards
Alex

Thanks @Alex_Law - appreciate you sending this over and no worries. Taking a look at this on my end now, I’ll loop back with you here once I have next steps to share

Alan_G · November 13, 2025, 9:51pm

Hey @Alex_Law - just checking in here. I noticed you mentioned you’re able to deploy using Rust. Just wanted to make sure, everything is alright on your end here - just let me know!
