Trying to shutdown deepAR to reuse it on another screen. However, it just crashes. ```auto Uncaught RuntimeError: memory access out of bounds at deepar.wasm:0x5003 at deepar.wasm:0xdb56f at deepar.wasm:0x91926 at deepar.wasm:0x12907b at deepar.wasm:0x13bfba at r._shutdownEngine (deepar.esm.js:1:1030115) at r.shutdown (deepar.esm.js:1:917512) at e.shutdown (deepar.esm.js:1:1971250) at Object.shutdown (index.ts:62:11) at eval (index.tsx:53:28) at safelyCallDestroy (react-dom.development.js:22932:1) at commitHookEffectListUnmount (react-dom.development.js:23100:1) at invokePassiveEffectUnmountInDEV (react-dom.development.js:25207:1) at invokeEffectsInDev (react-dom.development.js:27351:1) at commitDoubleInvokeEffectsInDEV (react-dom.development.js:27324:1) at flushPassiveEffectsImpl (react-dom.development.js:27056:1) at flushPassiveEffects (react-dom.development.js:26984:1) at commitRootImpl (react-dom.development.js:26935:1) at commitRoot (react-dom.development.js:26682:1) at performSyncWorkOnRoot (react-dom.development.js:26117:1) at flushSyncCallbacks (react-dom.development.js:12042:1) at eval (react-dom.development.js:25651:1) ``` ---

Is it possible to change `canvas` without reinitializing DeepAR? ---

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 > [@Web SDK Memory Out Of Bounds exception](https://forum.deepar.ai/t/web-sdk-memory-out-of-bounds-exception/31): > > 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? ---

We use npm package for DeepAR. `node_modules_deepar_js_deepar_esm_js.js` has: ```auto content-type: application/javascript; charset=UTF-8 content-encoding: gzip ``` `deepar.wasm` has: ```auto content-type: application/wasm content-encoding: br ``` And there is no `deepar.js` in network requests ---
