Depending on what NI DAQ device your application uses and also I/O type of the channel, certain terminals will only accept certain inputs.
In the body of the error message, Property will let you know what terminal on the DAQmx Function is reporting the error, Requested Value indicates what value you are currently attempting to pass, and Possible Values informs what an acceptable input would be. Changing the value to one of the Possible Values will resolve this error. If running a Shipping Example, verify the device you are using is supported with that example by checking under its "Requirements" section in the NI Example Finder.
