Bug in Post Request Node

Hello,

An error occurs when using the POST Request node if you try to use flow variables in the request header.

Figure 1: Entering the value directly; the POST request works.

Figures 2 and 3: Selecting a flow variable for "X-Authorization" results in the value not being displayed; clicking "OK" and closing the dialog immediately triggers an error message.

Figure 4: Error message. If you open the settings, the content of the flow variable has been applied to the first request header.
