How to get the FN and LN if not present in source?

HI

I have a scenario where i need to take the FN and LN from the particular source if not present take from the differnet attribute from the same source. If present the email should be fn.ln@email.com else the new fn.ln@emailcom.

I have tried with FirstValid and static but it throwing the seaspray template error.

Thanks.

Can you put the code here so that i can check where you missed the values or something…

I have checked with the JSON validator it looks fine for me.

Have you check the null values sometimes if you haven’t check the null values it may through the error

Nope i haven’t given that le me rectify that and let you know if it works. Thanks for the input @Santhakumar.

Sure. Always check the null values in the firstvalid transform.
