Error: exit status 1. (Uart-0 node. Uno R4 Minima)

Hello
I have a normal USB-C cable from the computer to the microcontroller. where I want to test if I can send data from the APP Inventor emulator to the microcontroller.

But I get an error when uploading.

The plan is to use a tablet to send data via OTG-USB.

Microcontroller: Arduino Uno R4 Minima

Program in XOD:

But when I upload I get this error code:

Error during build: exit status 1

Same error code if I instead uses SOFT-UART(D0=RX and D1=TX) /UART0-1 -Nodes…

Here is some information about USB/UART:

I have tried googling my way to a solution. but I haven’t found anything that made sense.

Hope someone can help

thanks in advance

I have tried to make a very simple code.

Which still fails:

The full error messags:

Is Arduino R4 Minima not compatible with XOD?
