Crypric error message when no board selected

Xinonix · August 4, 2022, 2:56pm

RC-9 - nightly-20220803

I got following very cryptic message:

grpc: error while marshaling: proto: Marshal called with nil

Compilation error: grpc: error while marshaling: proto: Marshal called with nil

Problem was I did not select a board....

### 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. [t3x_test_ftm_pin_capture-220717a.zip](https://github.com/arduino/arduino-ide/files/9128089/t3x_test_ftm_pin_capture-220717a.zip) ### 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](https://github.com/arduino/arduino-ide/issues?q=) - [X] I verified the problem still occurs when using the latest [nightly build](https://github.com/arduino/arduino-ide#nightly-builds) - [X] My report contains all necessary details

There is a related issue tracking the fact that even the intended error message under these conditions is not very easy to understand:

## Describe the current behavior On the first use, no board is selected. A ne…w user may not realize it is necessary to select one. If they attempt to compile a sketch without selecting one, they will receive only this cryptic error message: ``` Compilation error: Missing FQBN (Fully Qualified Board Name) ``` and this notification: ``` Error: Request compile failed with message: Compilation error: Missing FQBN (Fully Qualified Board Name) ``` This doesn't mean anything to even very advanced IDE users, and the user will have difficulty understanding what they need to do to resolve it. ## To reproduce 1. Quit the IDE if it is running. 1. Simulate a fresh install by deleting the configuration folder: - Windows: ``` C:\Users\<user name>\AppData\Roaming\arduino-ide\ ``` - Linux: ``` ~/.config/arduino-ide/ ``` - macOS: ``` ~/Library/Application Support/arduino-ide/ ``` This step is done because the IDE currently makes it otherwise difficult for those with internal serial ports to achieve the required state of having no port selected, due to the odd fallback port selection behavior (e.g., https://github.com/arduino/arduino-ide/issues/180). 1. Start the Arduino IDE. The board/port selector menu should show "**:x: No board selected**". 1. Select **Sketch > Verify/Compile** from the Arduino IDE menus. ## Describe the request Show a user friendly error message. Something like: > No board selected. Please select your Arduino board from the **Tools > Board** menu. ## Desktop - OS: Windows 10 - Version: 2.0.0-rc3-snapshot.1d88263 Date: 2022-01-24T16:22:30.529Z CLI Version: 0.20.2 [13783819] ## Additional context Even among Arduino CLI users, I have found that the concept of "FQBN" is not widely known. IDE users are even less likely to be familiar with this acronym, and even less anxious to spend their time learning what it means, since the it is not otherwise a part of the IDE user experience. --- Note that the error message produced by the reproduction instructions above is currently different than described due to a recent regression in Arduino CLI: https://github.com/arduino/arduino-cli/issues/1812 ### Related - https://github.com/arduino/docs-content/issues/300
