when prompts nodes are used what is the validation that is checked say when Name node is used how does the validation works, like it only checks the data type or something else as well  
please refer the Screenshot, name node is used here, till user doesnt give any input as string the validator gets triggered.

Hi @Dipanjan_Datta Name node validators works on data type used in the input provided by end user.
