How to check if the value of a field is null?

[Pedro_Malaquias]

Hello everyone, everything good?
This time I would like to know how I can make a flow check if the return of a field is not null or empty, as I only need the information to be passed on when the field is not empty.
Below I’m using the example of an array of birthdays, and the last ones have an empty “date” and/or null, how do I do that?

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):
• Running n8n via (Docker, npm, n8n cloud, desktop app):
• Operating system:

@Pedro_Malaquias , the condition is called just that, “Is not Empty”, which implies “not empty string and not null”.
