I have trouble to parse 32bit Value using buffer-parser node

This is the Input:  
[ff,ff,ef,a0]

SyntaxError: Unexpected token f in JSON at position 2

My expected Value is:  
-4192

Thanks for help  
Joseph

We are good, but I'm afraid we are not mind readers 🙂

You will have to share the data going into the buffer-parser and how you have it setup (at minimum) for us to help you.

For a buffer input you have to convert into decimal numbers.

Then your buffer node does what you expect:

Or use strings `["0xff","0xff","0xef","0xa0"]` ...

Thank you Steve,

I have seen, the Problem was the inject-node sending the error (not the 'buffer parser')
