Hello there,
I am facing system.StackOverflowExcepiton while exporting document with HtmlFormatProvider. I am attaching my code with the HTML string which I am passing into RichTextEditor.
---------------------------------------------------------
HTML String:
"Navigate to the <a href="https://exelon.ifs.cloud/landing-page/" target="_blank"><b><u>IFS Cloud Landing Page</u></b></a>.<br /> <br />NOTE: If the above link does not work for you, copy and paste this address ...<br /> <br /><u>https://exelon.ifs.cloud/landing-page/</u>"
