AWS Amplify throws exception while running hosted Blazor WebAssembly

The exception you're encountering indicates an issue with the WebAssembly (Wasm) content in your Blazor WebAssembly app. It appears that the Wasm file is not being recognized with the expected content type, which is causing the instantiation error.

To resolve this issue, you can try the following steps:

1. Verify Wasm Content Type: Ensure that the Wasm file in your app has the correct content type set to "application/wasm". Double-check the file's metadata or settings to confirm this.

2. Check Amplify Hosting Configuration: Review the configuration in AWS Amplify for hosting your Blazor WebAssembly app. Ensure that the hosting settings are correctly configured to recognize and serve Wasm files with the appropriate content type.

3. Clear Browser Cache: Sometimes, the browser cache can cause issues with loading updated versions of Wasm files. Clear the cache in your browser and try running the app again to see if the issue persists.

4. Update Amplify Build Settings: If you made any changes to your Blazor WebAssembly app's build process, such as modifying the build settings or including additional dependencies, make sure these changes are correctly reflected in the AWS Amplify build configuration.

5. Test Locally: Try running your Blazor WebAssembly app locally to ensure it works as expected without any Wasm-related errors. This can help isolate the issue and determine if it's specific to the hosting environment or the app itself.

6. Seek Amplify Support: If the issue persists, consider reaching out to AWS Amplify support for further assistance. They can help investigate the specific details of your setup and provide guidance on resolving the Wasm instantiation error.

By following these steps, you should be able to address the WebAssembly-related exception and successfully run your Blazor WebAssembly app on AWS Amplify.
