Hello,

I am getting the below error in invoke code.

I want to save the text file into PDF.

No null values are passed and but still error throws.

InputFile: "C:\Users\Karthikeyan\Documents\UiPath\CSACustomerService_Dispatcher\Data\Input\MailasPDF\MailPDF.txt:

OutputFile:
“C:\Users\Karthikeyan\Documents\UiPath\CSACustomerService_Dispatcher\Data\Input\MailasPDF\MailPDF.pdf”

The image shows an error message "Invoke Code: Exception has been thrown by the target of an invocation." in a code editor where VB.Net code is being used to automate Microsoft Word operations. (Captioned by AI)

hie @sharu_priya can you show the arguments that you are passing what value that has been holding.

cheers

Sure.

The image shows a dialog box named "Invoked code arguments" with two input arguments, "InputFile" and "OutputFile", both of type String and assigned to "str_MailTextPath" and "str_MailPDFPath" respectively. (Captioned by AI)

Can you try to add try catch in your code so it will give you the exact exception.and also insure that microsoft is installed in your machine where you are running the code.

cheers

Below is the input file. I think this is not the word file i guess.

This image shows a file explorer window with the path "C:sersarthikeyanocumentsiPathSACustomerService_DispatcheratanputailasPDF" displaying a single text document named "MailPDF" with a size of 67 KB and a modification date of January 30, 2025. (Captioned by AI)

Note: This code is not developed by me. So little confused

Hey @sharu_priya can you use alternate method like read word and save it to text file.

A process flow chart shows a Word Application Scope reading text from "Input.docx" and writing it to "Output.txt". (Captioned by AI)

Hi Sumit,

I contacted the developer of this code.

He suspected that it might be the size of the input doc is large… so it may not get converted to PDF.

Regards,
Sharu
