Copy and Pasting Large Text Crashes the Application

Hello Team,

I've been testing the copy and paste and it seems to be working fine until I copy and paste a long text. The application freezes and crashes and I've tested this on blazor as well and it does the same thing. What could be the issue here?

Hi William,

We suspect that the reported problems are might be due to the contents in the input word document which used at your end. We need to investigate with the contents in your input Word document to reproduce the exact problem at our end. So, could you please provide us the input Word document which used at your end and also share the details of issue if you faced any in console. Thereby, we will analyze further and provide you the appropriate solution at the earliest.

Note: If you have any confidential data in your Word document, please replace with some dummy data and provide us the same. We just need your document to recreate the problem you face.

Hi Selvaprakash,

There is nothing special about the contents I copied and pasted, they were just words I typed in. when I copy and paste just few words it is fine but as soon as I copy a whole paragraph, the application crashes. Below is the error I get in console when this happens.

William, we recommend you use the below code to resolve the copy and paste long text issue. 

builder.Services.AddServerSideBlazor().AddHubOptions(o => { o.MaximumReceiveMessageSize = 102400000; });
