How to fix the error "Invalid type definition: Cannot set properties of null (setting 'name')"?

[Vrinda R]

Hi,

While building blink code on the NRF5340DK, I get an error "Invalid type definition: Cannot set properties of null (setting 'name')" like this in visual studio.

Could you please help me to resolve this?

Thank you

Hi,

Try applying this change: https://github.com/zephyrproject-rtos/zephyr/pull/55877/files

I have the same problem.  The update above of file v2.3.0/zephyr/dts/bindings/serial/amr,sbsa-uart.yaml does not fix the problem.

I have the same Issue with 2.3.0 SDK and nRF52840 dev board, following the blinky_pwm tutorial

Hold the phone!  After either the restart of VS Code, or reboot of Windows 11, or both, the fix has eliminated the error.  Can't explain it, but that's the observation.

In case this helps anyone SDK 2.3.0 missing the last line in the arm,sbsa-uart.yaml file.

Adding it back in (was there in earlier SDKs) enabled output in the Terminal window for me.

Thanks,

"required: false" was missing for interrupts in file v2.3.0/zephyr/dts/bindings/serial/amr,sbsa-uart.yaml
