Uploaded our build to the appstore. This took many tries, as we saw it hang during “validating” many times, infinite poll of some `upload-status` endpoint in browser network console. Eventually, it went through, this time we got this error: ![image](https://d3mq594dkmpl37.cloudfront.net/original/2X/b/bbfce13b214ff5435ac51ef10b4cdeb21d6af4ee.png) Which leads to this page: [https://developer.amazon.com/docs/kepler-tv/app-submission.html](https://developer.amazon.com/docs/kepler-tv/app-submission.html) Which is a 404 ---

Hi @mikey, Thank you for bringing this to our attention and for providing the information about the upload issue. **Please refer to the correct Vega app submission documentation here:** - [App Submission](https://developer.amazon.com/docs/vega/0.21/app-submission.html) - [Test Your App Before Submission](https://developer.amazon.com/docs/vega/0.21/test-before-submission.html) - [App Submission Requirements](https://developer.amazon.com/docs/app-submission/submitting-apps-to-amazon-appstore.html) Let me know if I can help with anything else. Warm regards, Aishwarya ---

Thanks, but we still don’t understand the error: “Invalid or missing build number in the VPKG”. Here is the pertinent part of the `manifest.toml` which was used to build this: ```auto schema-version = 1 [package] ... version = "1.2.5" ... ``` In general, whatever the answer is, similar to the [other issue we just reported](https://community.amazondeveloper.com/t/bad-icon-file-path-in-manifest-leads-to-cryptic-installation-error/25116) errors like this need to be reported much earlier in the development process—at compile time and by the SDK, not at submission time & by the appstore. ---

Also, I don’t see the version field [documented in the `package` docs](https://developer.amazon.com/docs/vega/0.21/manifest-package.html). But this is what the sample apps use, and the string we set here _is_ being returned by `getVersion()` from `@amazon-devices/react-native-device-info`. ---

New guess: we need to _additionally_ pass the version as a flag to `build-kepler` as described here: [Version Your App | Design and Develop Vega Apps](https://developer.amazon.com/docs/vega/0.21/app-version.html#from-the-command-line) That’s cumbersome since this is something we already check in with (a) `package.json` and (b) `manifest.toml` (though that might be unsupported and misleading from the example apps). I’ll file a separate feature request. ---

Hi @mikey, You’re correct - the version needs to be passed as a flag to `build-kepler` as documented here: [https://developer.amazon.com/docs/vega/0.21/app-version.html](https://developer.amazon.com/docs/vega/0.21/app-version.html) For example, to build your app with version 1.2.5, use: ```bash build-kepler --version 1.2.5 ``` This should resolve the upload error you’re experiencing. Our team is looking into the request and will provide an update as soon as we have more information. Thanks for helping us improve the Vega platform. Warm regards, Aishwarya ---
