Error while running Spire.PDF on AWS Lambda Environment

[sumit.pundhir]

Hi Team,

I am using Spire.PDF v6.11.6 to convert PDF to PDF/A compliant document. I am able to build and run the code on Windows machine however when i am trying to run the same code on AWS Lambda environment[Linux OS], its failing.

Platform user: .Net Core 3.1

Code:
PdfStandardsConverter converter = new PdfStandardsConverter(tempFileName);
converter.ToPdfA1A(tempFileName1a);


i am getting below error:

Error while converting file:System.TypeInitializationException: The type initializer for 'sprᜬ' threw an exception.
---> System.InvalidOperationException: Cannot found font installed on the system.

Can you help me out to fix this issue. I believe Spire.Pdf class is trying to find the Fonts on linux application but its not available so failing. Can i get a solution of this issue?

Hello,

Thanks for your inquiry!

Kindly note that when the fonts are not embedded in Pdf document, the fonts used in the document must be installed on Linux OS. Because in this case, our Spire.Pdf will read fonts data from Linux OS according to the fonts name in the document during converting, if we cannot find the matching fonts or similar fonts in the Linux OS, the program will produce the issue you mentioned.

From your error message, the fonts in your Pdf should be not embedded in the document, so please install the fonts used in your Pdf on your Linux OS (or you could copy the fonts on your Windows machine to Linux OS) and then try to run the program again. If the issue still exists, please provide us with your input Pdf document for investigation. Thanks in advance.

Sincerely,
Marcia

Hi,

After installing the program works but there seems one issue as the converted pdf is having few text lines missing.

Not sure why this happening, i am using below code:

PdfStandardsConverter converter = new PdfStandardsConverter(file.ToString());
converter.ToPdfA1A(outputTo1A);
converter.Dispose();
document.LoadFromFile(outputTo1A);
document.FileInfo.Version = PdfVersion.Version1_3;
document.SaveToFile(outputTo1A);
document.Close();

we are running the code in Linux .net core 3.1 environment.
