Word With Table- Viewing problem

GroupDocs.Viewer Product Family
1

Hi, when we try to view a word document that contains table, document turns into a string and we cant view it normally.
Problem does not happen when we run our app on local. But when it runs on server we get this problem at the image

Thank you for sharing the package version. I have failed to reproduce this issue alone with GroupDocs.Viewer for .NET 23.6 which renders the document without issues.

After checking the Network tab in developer tools I have found that the output pages are pre-processed on the server side so only <body></body> contents is sent to the client see network-tab.png (192.1 KB).

The fix could be the following:

  1. Search for <body> in your codebase.
  2. Remove a code that handled extracting <body> contents and return the complete HTML document without modifications.

Please let us know if it works for you.

I think data we received from LoadDocumentDescription is corrupted.
When we look deeper we can see there is a get content method :

This brings normal HTML data when we are on local windows PC ,
But when it comes from server we receive this:

As you can see characters are coded like "\uFEFF\u003C " .Probably its related to character codings. Do you have any advice?

Can you check what value has Data variable from the first snip?

I belive you are asking this. Or should I send the byte array?

@Kuropetti

Thanks, what OS you’re running the app on?

Serverside is linux . My lcoal is windows
but we have same encoding decoding problem on local.

For example:
I send getViewerLink request including download url via postman to my local viewer app .
Getting that response and viewing that document on local works fine.

But when I look into browsers network , the page data returned by the LoadDocumentDescription response is like this:
image.png (12.8 KB)

Same data, viewson on local normally, but not on the production environment

@Kuropetti

The issue with encoded characters may be resolved by using JavaScriptEncoder.UnsafeRelaxedJsonEscaping encoder instead of default one.

In case you’re using GroupDocs.Viewer.UI you can update roupDocs.Viewer.UI.SelfHost.Api to 6.0.23 where I have updated the encoder in this this commit.

<PackageReference Include="GroupDocs.Viewer.UI.SelfHost.Api" Version="6.0.23" />

Unfortunately, this change can’t fix the issue with table since <head> that is stripped from the response contains styles for the table.
