Using variables to program Eztimer error: Invalid object (msg.payload) input

Trying to program Eztimer on and off time without success, I assume the problem is with the input to Eztimer not being the right type, I have tried converting object to JSON string with JSON node and also using mustache template but no success?

error

According to the read me at node-red-contrib-eztimer (node) - Node-RED , the ontime and offtime should be object properties of msg.payload.
e.g msg.payload.offtime.

Hi E1cid thanks for the reply, I tried that first same error.
