Request body too large - servicestack

Question

When I try to upload a 80mb file from postman to my local endpoint running in Visual Studio 2019 on IISExpress I get the following error:
The request filtering module is configured to deny a request that exceeds the request content length.
So I added this to applicationhost.config for the project:
<system.web>
<httpRuntime maxRequestLength="1050000" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<requestLimits maxAllowedContentLength="1073741824"/>
</requestFiltering>
</security>
This stop the error coming when I make the API request but now I just get a ServiceStack generated "snapshot" page telling me how long request took and the date but my actual endpoint is never hit.
Inside my logs I can see ServiceStack throwing this exception:
2020-07-20 01:57:56.0497||ERROR|ServiceStackHost|Request body too

So the Body length still needs to be set somewhere but everywhere I look points back to the config I have already used.
Is there additional setting required or is this a ServiceStack issue?

Answer 1

I was missing this option in startup:
services.Configure<IISServerOptions>(options =>
{
options.MaxRequestBodySize = int.MaxValue;
});
services.Configure<KestrelServerOptions>(options =>
{
options.Limits.MaxRequestBodySize = int.MaxValue; // if don't set default value is: 30 MB
});
