Web Document Builder API debug

Hello. I want to use “web document builder service” ONLYOFFICE Api Documentation - Web Document Builder API .

I’ve installed Installing ONLYOFFICE Docs for Debian, Ubuntu, and derivatives - ONLYOFFICE on Linux debian 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29) x86_64 GNU/Linux.

builder.CreateFile("docx");                 // create a text document file in the .docx format with ONLYOFFICE Document Builder
var oDocument = Api.GetDocument();          // create a new 'oDocument' variable and get the created text document contents
var oParagraph;                             // create the 'oParagraph' variable
oParagraph = Api.CreateParagraph();         // create a new paragraph
oParagraph.SetJc("center");                 // set the paragraph justification to center the text
oParagraph.AddText("Center");               // add a text containing a single 'Center' word to the paragraph
oDocument.Push(oParagraph);                 // push the created paragraph contents with the 'Center' word to the document
builder.SaveFile("docx", "example.docx");   // save the resulting text document as a file in the .docx format with the 'example.docx' name
builder.CloseFile();                        // close the text document file and finish work with ONLYOFFICE Document Builder

Script is ok because I’ve checked it on standalone documentbuilder which do as expected.

  1. Does ONLYOFFICE Docs Community Edition include “web document builder service”?

  2. If it does – how can one find out more than “error code -4” and troubleshoot it?

Hello @unam3

Yes, Community Edition of ONLYOFFICE Docs is also packaged with built-in Document Builder.

Most common error codes and their description are listed on the bottom of Web Document Builder API page that you’ve already provided.

-4 Error while downloading the document file to be generated.
