Compilation error: grpc: error while marshaling: proto: Marshal called with nil
Describe the problem
Sorry there is probably something screwy in this code, that I am hacking up...
I tried to do a verify operation, and the build aborted with an error:
grpc: error while marshaling: proto: Marshal called with nil
Compilation error: grpc: error while marshaling: proto: Marshal called with nil
That was all of the output, all in orangish color.
I have no idea what that error is supposed to imply.
To reproduce
Not sure, but I included the code... Note: this code is not done yet, nor may never be used, but just an experiment on Teensy 3.2, to see if I can use FTM timer to capture pulse widths and maybe generate specific pulses...
I simply clicked on verify with this sketch, which includes a header file, which is part of the sketch.

Expected behavior
I am guessing probably lots of error messages.
Arduino IDE version
20220716
Operating system
Windows
Operating system version
Windows 10
Additional context
I am running with yesterdays IDE did not see any updates for today.
Issue checklist
- [X] I searched for previous reports in the issue tracker
- [X] I verified the problem still occurs when using the latest nightly build
- [X] My report contains all necessary details
I believe I figured it out what happened.
Before this I had done a SaveAs operation to this new name. The code hung with spinning ... So I closed out the window (and process). Restarted IDE. Browsed to the new saved file and tried to do the compile...
But turned out it had forgotten I was building for T3.1/2 and had the simple chose board... in drop down list. Going back up and choose T3.1 now it behaves normal...
Side note: Thought maybe had issue with the new sketch name. So I exited the IDE, used browser to rename the directory and sketch to different name. I then restarted the IDE. Looks like it had issue with not finding the last sketch that was last edited, and gave me a blank window... Also the Sketchbook tab area showed as empty, but was able to go up to File ->Sketchbook and open up the sketch with the new name.
had the simple chose board... in drop down list.
Do you mean the "❌ No board selected" like this?
I gave it a try but I only got the expected "Missing FQBN" message rather than the unexpected error you reported.

I guess it is the same issue you reported at https://github.com/arduino/arduino-ide/issues/1089. That will be fixed by https://github.com/arduino/arduino-ide/pull/1152
Maybe, I just reproduced it.
I was verifying fine... Then I decided to program a board, so I turned it on, and tried to compile and it warned that I need to select a board...
I then clicked on the drop down list (select board), which brought up dialog where you can choose the board type..., I then canceled, the dialog.
I then tried to do a verify and got that error.
OK, I am able to reproduce it now. I was using a slightly outdated version of the IDE before.
This was a regression introduced by https://github.com/arduino/arduino-ide/commit/73835eced3bda7657308bf582bd5e5690d73879a.
The menu item text was also just changed, but by a different commit unrelated to this new unpleasant error message.

It's tracked here: https://github.com/arduino/arduino-ide/issues/1204
I determined this is a bug in the Arduino CLI codebase, so I have moved the issue to the appropriate repository.
I bisected the issue to a5466d017f7767226b090ed9d3e0b8a74617e0da
In case it will be useful, I will provide instructions for reproducing the issue using the Arduino CLI gRPC interface directly (the issue does not occur when using the Arduino CLI command line interface).

ERROR:
Code: Internal
Message: grpc: error while marshaling: proto: Marshal called with nil
Since the fqbn
field was omitted from the cc.arduino.cli.commands.v1.ArduinoCoreService.Compile
request, an error is expected. However, it should be the slightly more user friendly "Missing FQBN (Fully Qualified Board Name)" error that was returned prior to a5466d017f7767226b090ed9d3e0b8a74617e0da.
