Hi,

I am new in Pega. I just try to make a custom Save button on a form. The action I use is Save. But, when I try to save the data with the custom button, it's give an error message "Key: Keys of Instance Value must be specified".

Would you help me please? Why was the error happen? And How can I fix that error? Thank you.
