Cannot find any fonts in specified font sources.

Hello,
We are trying to convert a DOCX to PDF using spire.doc v12.3.12 in .net8 and we are getting this error:

System.InvalidOperationException: 'Cannot find any fonts in specified font sources.'

The code I am using is as follows:

string subPath = "wwwroot/temp/";
Spire.Doc.Document doc2 = new Spire.Doc.Document();
doc2.LoadFromFile(@subPath + "/" + formSubmissionId.ToString() + ".docx");

bool fileexists = System.IO.File.Exists(subPath + "/" + formSubmissionId.ToString() + ".pdf");

if (fileexists)
System.IO.File.Delete(subPath + "/" + formSubmissionId.ToString() + ".pdf");

//Convert Word to PDF
doc2.SaveToFile(subPath + "/" + formSubmissionId.ToString() + ".pdf", FileFormat.PDF);

I have uploaded a sample word document with some details modified to protect the user.

If you need anything else, please let me know.

Thanks
Michael

Hi,

Thanks for your inquiry.
According to the exception message(Cannot find any fonts in specified font sources.), the reason of your issue is that the fonts used in Word file don’t exist in the server. Please put these fonts into system font folder then test again, if your server is Linux system, the system font folder is

Code: Select all

/usr/share/font.

Sincerely
Abel
