Template &1 node id &2 attribute &3 type code &4 no text search

What causes this issue?

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

Due to UI problems, we do not recommend using the datattype "dateTime"
and setting the "TextSearchIndicator" in the attribute section to true.
If you want to use text search for timestamps, you should create an
extra field containing the timestamp in all active time formats of the
end users. You can include this field in the request (not the response).

How to fix this error?

Change your model as proposed above.
