System.NullReferenceException saving in DOCX

[Nirav_1992]

Hi,

I have a template in DOCX format where we have formfields in the template. We have a value that has carriage returns in it and values are mapped to form fields. So while saving the file in Docx format getting the below error.

Note - Same functionality works for PDF and DOC

System.NullReferenceException: Object reference not set to an instance of an object.

Hi,

Thanks for the update.
We have tried with both versions -Spire.Doc 11.3.1 & 11.4.0, but still, the issue persists.

I am sharing the sample project where this issue is getting replicated.
Can you please check with a sample project attached to the post?

Hi,

Thank you for your feedback.
Sorry, as you did not provide any document or code earlier, we only made the compatibility for a single '\r'. I have re-logged your issue with ticket number SPIREDOC-9283. Additionally, I have tried saving in the doc format and found that line breaks'\r\n' are displayed as garbled characters. Would it be acceptable for us to make docx compatible in the same way? If not, please provide the desired output effect, which I will submit to our development team for investigation on whether it can be achieved. Sorry for the inconvenience caused.
