Rgb_color variable, how to?

Third party integrations Node-RED

Hi,

I have a call service node with the following datafield:
{"brightness":255,"rgb_color":[0, 255, 191]}

I want to use the rgb_color variable. I have a random color node in front of it with an output payload like e.g.: {"_msgid":“6e6499ddef0f2ef7”,“payload”:"[17,147,163]",“topic”:""}

What would be the correct notation for the data field in the call service node to use the payload with the random number from the previous node?

Never mind, found my issue… sorry… It was not Json, now it works:
