HTTP Request node - Predefined credential

[PPCM]

The module works fine using standard fonctions (in particular GET on products)

But I need to update a field, and in PATH function, there is no ability to update specific fields, so I need to use HTTP Request with a Predefined credential
With that the credential failed

"status": 
"rejected",

}
}
}

I tryed with a simple GET to get product information (working with the node function) and it failed to with the same error

In the debugging console, we can see

Do I need to add something in the header?
Thanks for your help
