Blazor WebAssembly.instantiate(): Out of memory: Cannot allocate Wasm memory for new instance

In my Blazor app I sometimes get this while running the app on a tablet:

23:46:03.521 blazor.webassembly.js:1 Uncaught (in promise) RangeError: WebAssembly.instantiate(): Out of memory: Cannot allocate Wasm memory for new instance

Any idea what I can do about this? Also seems like it sometimes throws this yellow error bar in the bottom and sometimes not.

Solution

  • Solved by setting below property in the .csproj file.

    <EmccTotalMemory Condition="'$(Configuration)'=='Release'">134217728</EmccTotalMemory>
