120163: The field type of <value> does not match the field type of the input layer. Expected <value>, but got <value>.

Description

An append layer field matches an input layer field name but has a mismatched type.

Solution

To append by default, verify that fields with the same name also share the same type.

Use the Append Expressions parameter to alter field values with Arcade expressions.

If you append using the Append Fields parameter, make sure Input Fields and Append Fields are the same type.
