Import of large sites fails

We're in the process of changing from CMS 11 to CMS 12 and want to start on a fresh database.

Therefore we want to use the Import data feature, how ever, we get the error "timed out or max file size exceeded".

I've tried multiple things:

web.config

<configuration>
	<system.webServer>

				<remove name="X-Powered-By" />
				<add name="X-UA-Compatible" value="IE=Edge" />
			</customHeaders>
		</httpProtocol>
	</system.webServer>
</configuration>

Startup.cs

// If using Kestrel:
services.Configure<KestrelServerOptions>(options =>
{
	options.Limits.MaxRequestBodySize = null;
	options.Limits.KeepAliveTimeout = TimeSpan.FromMinutes(60);
	options.Limits.RequestHeadersTimeout = TimeSpan.FromMinutes(60);
	options.AllowSynchronousIO = true; // NewtonSoft.Json issue
	options.AddServerHeader = false;
});

// If using IIS:
services.Configure<IISServerOptions>(options =>
{
        options.MaxRequestBodyBufferSize = int.MaxValue;
	options.MaxRequestBodySize = null;
	options.AllowSynchronousIO = true; // NewtonSoft.Json issue
});

// uploading options for EPi
services.Configure<UploadOptions>(options => options.FileSizeLimit = 4294967295L);

Startup.cs

app.UseWhen(context => context.Request.Path.StartsWithSegments(new PathString("/EPiServer"), StringComparison.InvariantCultureIgnoreCase), builder =>
{
	var maxSizeFeature = builder.ServerFeatures.Get<IHttpMaxRequestBodySizeFeature>();
	if (maxSizeFeature is null)
	{
		return;
	}
	maxSizeFeature.MaxRequestBodySize = null;
});

How big is your file, and what is exactly the error message (including stacktrace if any?)

Hi Quan,

Everything over 30MB fails. - But some of our sites is 4 GB or so.

Setting 'MaxRequestBodySize' to null is supposed to fix the issue.

No error message in logs. Only the visual message in backoffice "timed out or max file size exceeded".

Hi Paul.

This setting only affects file uploads in the media folders.
And I've already set this by code:

// uploading options for EPi

Have you tried it with just that configuration setting?

I have this in my current projects and it is working:

"EPiServer": {
"CmsUI": {
"Upload": {
"FileSizeLimit": 104857600
}
}
},

Are you running this under a linux OS?

Carl S - Jul 03, 2023 8:33

No I have not. Setting it by code should be enough. But I can try that.

No. Windows and IIS.

Carl S - Jul 03, 2023 8:38

Your suggestion to add only configuration setting did nothing. Same error.

Just to be sure, did you combine both settings (in IIS and in application layer)?

Carl S - Jul 03, 2023 9:36

Combine both settings? :)

Quan Mai - Jul 03, 2023 9:40

yes, basically enable the big files upload on both IIS and on application layers.

Carl S - Jul 03, 2023 9:45

I have tired multiple variations. But yes.

remove name="RequestFilteringModule" is supposed to remove the max file limit in IIS.

Have also tried requestLimits maxAllowedContentLength="4294967295" in web.config.

And you can see by my code - setting 'MaxRequestBodySize' to null is also supposed to remove the max file limit.

A shot in the dark, but maybe this in addition of your current settings

            services.Configure<FormOptions>(x =>
            {
                x.ValueLengthLimit = 5000; // Limit on individual form values
                x.MultipartBodyLengthLimit = 737280000; // Limit on form body size
                x.MultipartHeadersLengthLimit = 737280000; // Limit on form header size
            });

Awesome. I set these to the max values and I could upload a 3 GB file.
Thank you!
