Your payload seems to be an array  
`payload: [true]`  
whereas it needs to be a boolean  
`payload: true`

If you could be confident that the value you want is the first element of the array, you could use a change node:

I have no knowledge of the FINS Read Multiple node, but looking at the name, I'd guess it might sometimes return an array with multiple elements. That's why I didn't make a suggestion in my first answer.
