We recently added a column to a PostgreSQL table using the money datatype. This caused our Zaps to stop working and “We’re having trouble …” messages that also state “(Can’t generate DDL for NullType(); did you forget to specify a type on this Column?)” but not the column name.
Problem solved by changing the properties of the Columns from Data type “money” to Data type “numeric” (without specifying any Length/Precision).
Thanks for sharing the tip with the Community 😀 Happy Zapping!
