Michael Chirlin - thanks, any chance Appian might come up with a remedy for this issue on the plug-in side?

FYI i didn't see your reply initially since Community apparently doesn't want to notify me for basic replies here.

Hi Mike,

Can you please tell me how do I configure fill PDF tool pluggin ? I need to create an editable form. Users will fill that pdf form with required values and submit. After submitting , we can download that newly edited pdf.

We recently upgraded to 20.3 and this plugin was dropped from our environments. A suitable alternative for our use-case was the smart service named PDF Doc From Template. (Use a PDF template to populate data into and save as a PDF file in Appian)

This error will show up when there is a versioning issue with the plugin cdt. If you look in your tomcat-stdout logs you'll see the actual issue.

Support will point you to https://community.appian.com/.../kb-1097-illegal-attempt-to-change-the-data-type-for-smart-service-x-x-x-input-or-output-named-name-error-thrown-during-plugin-deployment

We are using the PDFBox library to insert the fields into the PDF.

You may be running into this issue:

This plugin is using the PDFBox java library: https://pdfbox.apache.org/docs/2.0.7/javadocs/org/apache/pdfbox/text/PDFTextStripper.html

If you are seeing issues, they will be present in that library and not fixable directly in the plug-in.

Was your question on how to modify this plug-in so that you can redeploy it on your environment?

Do you mean for Create PDF Smart Service? Here's an example configuration that produces the following image. You will need to adapt the rules to use the equivalent data types (e.g. rule!PdfText to type!PdfText)

Example PDF.txt
