Issue with Boolean / Two Option Set field. A binary operator with incompatible types was detected.

[carterbarry88]

I came across the following issue with my trigger:

A binary operator with incompatible types was detected. Found operand types 'Edm.Boolean' and 'Edm.Int32' for operator kind 'Equal'.

I was trying to do the following for the filter expression:

new_booleanfield eq 1

In order to fix this, I changed the filter expression to new_booleanfield eq true

You cannot use the option set value for the boolean field. You have to use true or false values
