I have assigned a user "FSL Dispatcher" profile and trying to Book an Appointment via that user but on clicking on "Get Appointments" i am getting attempt to dereference a null object error. Am i missing some permission or some records are missing which are required to get appointments. When i am doing this via System Admin profile, i am not getting any error.
See here. Looks like Salesforce has a knowledge topic on the situation. https://help.salesforce.com/articleView?id=000264820&language=en_US&type=1
