Hi, you do typically need to shutdown deepar to reinitialize with a different canvas

Can you check the metadata headers settings (Content-Encoding and Content-Type) for .js, .wasm, model and effect files on your server. This error usually happens on startup, but try checking out the thread dedicated to it

> If you get this error while using DeepAR on your domain, you should check the metadata header settings (Content-Encoding and Content-Type) for .js, .wasm, model and effect files on your server. These are explained in the [getting started guide](https://docs.deepar.ai/deepar-sdk/deep-ar-sdk-for-web/getting-started) You can also Inspect your page and compare the metadata headers to one of our [demo examples](https://sdk.developer.deepar.ai/virtualTryOn/index.html). This should make it any mismatches easier to spot.

If that doesn’t help, can you share some of your shutdown code so we can check for potential issues?
