Node-red payload

Boa tarde, alguem me consegue ajudar, eu quero imprimir do meu payload todos os elementos que estão em _value mas quando faço msg.payload._value ele da me "undefined" mas qunado eu faço msg.pauload[0]._value ele imprime so do primeiro object como faço para imprimir todos?

tentei usar uma função mas nao deu resultado

Bom dia @a45293.

Use a Change node like this:

Hoje estou em Londres. Amanha, Rio!
:umbrella: :uk: :airplane: :brazil: :sun_with_face:

Send your data through a split node & you will get every value in the array as a separate message.

Then, if necessary, use a change node to adjust the payload.

Finally, if you want them back as once result, use a join node


If you want me to prepare a demo flow, copy and paste some sample data into a reply by using the "copy value" button

can you hel me with a template to display all my pics this is my old template

<img width="30" height="30" src=  {{msg.original._value}} alt='Image not found'  />

You have no quotes around the value for the src attribute

src="{{msg.original._value}}"

but this just print one of my pics and i need all
