I have a column with type blob in my form. To this I need to add the PDF file. I have also tried with the datatype CLOB.

But this is not working. It is showing the error like
Column "CREDIT_APP_FORM" specified for attribute "<div class="t-Form-labelContainer"> <label for="#CURRENT_ITEM_NAME#" id="#LABEL_ID#" class="t-Form-label">Credit Application Form <span class="u-VisuallyHidden">(Value Required)</span></label> #HELP_TEMPLATE# </div>" has not been found in data source!
How to resolve this error. Can anyone please help me to fix this error?
