Hi , To fix the Issue to allow max character's In the request, you need to make below changes In wwwroot folder.
By default Request Limits value for the maxAllowedContentLength on IIS which is 30000000 (roughly 28.6MB) in Azure web app. To modify this value, add the following to your web.config file. And add this file under wwwroot
- Create web.config file in wwwroot folder If not exists and then add the below settings In that config file
<configuration>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="<valueInBytes>"/>
</requestFiltering>
</security>
</system.webServer>
</configuration>
- Mention the value how much you would like to allow in maxAllowedContentLength
- Save the changes , restart the Appservice and test the application.
