Hi Rhianne,

Examining the provided documents it seems there are missing required named destination objects in their structure which leads to the observed exceptions. The "Name" for the first and third GoTo actions is not registered in the document`s Names (NamedDestination) collection:

I could suggest handling this exception using the handling mechanism described in the Handling Exceptions help article or:

PdfFormatProvider provider = new PdfFormatProvider();
provider.ImportSettings.DocumentUnhandledException += this.ImportSettings_DocumentUnhandledException;
this.fixedDocument = provider.Import(str);

private void ImportSettings_DocumentUnhandledException(object sender, DocumentUnhandledExceptionEventArgs e)
{
	if (e.Exception.Message == "Value cannot be null.\r\nParameter name: action")
	{
		e.Handled = true;
	}
}

I hope this helps. Please, let me know if there is anything else I can assist you with.

Regards,
Martin

Effected documents have been attached. The error are not directly loaded from the files.

The fillable fields on the pdf are filled with client data before being flattened and saved as a byte array. The error is occurring when we trying to view these specific pdfs from the byte array.

Here is the stack trace in case this helps

Hello Rhianne,

Would you be able to provide us with the document in question so I can inspect it, try to reproduce the results you are experiencing, and identify its cause? I can assure you that anything shared by our clients is treated with strict confidentiality and is used for testing purposes only (as per our EULA section 11).

I am looking forward to your reply.
