I launched the Arduino IDE from a command line and watched the stdout.

2024-01-14T03:57:44.657Z root ERROR Detected an error response during the gRPC core client initialization: code: 9, message: Loading index file: loading json index file c:\Users\x\AppData\Local\Arduino15\package_drazzy.com_index.json: open c:\Users\x\AppData\Local\Arduino15\package_drazzy.com_index.json: The specified file cannot be found.`

I looked into c:\Users\x\AppData\Local\Arduino15\ and interestingly, I can see a file named package_drazzy.json but not package_drazzy.com_index.json. This is a mismatch from the filename in the URL.

I do see a file named package_esp8266com_index.json which matches the ESP8266 board URL filename.

I did an experiment and copied the package_drazzy.com_index.json file onto my own web server, but I renamed it as package_drazzycom_index.json removing the dot like ESP8266 does.

And this fixes the issue! So there is a problem with the filename of the library!

To be 100% sure, I renamed package_drazzycom_index.json to package_drazzy.com_index.json (with the dot) on my webserver, and it stops working just like the official URL.

That's a problem... not sure what behavior is correct. I notice that the ESP32 arduino board URL is https://espressif.github.io/arduino-esp32/package_esp32_index.json and it does not have multiple dots. So I presume that multiple dots in the URL is the issue.

If so, I think a suitable solution would be:

• First, contact Arduino and verify if it is not a bug with IDE 2.2.1. If it is and they accept to fix it, just wait for them to do it and post a notice on the project page for users to use another version.
• If it is not a bug of the Arduino IDE, for instance if they specify to not use multiple dots, then you should start telling users to use a new URL without the dot like I did above, and you will have to keep both copies active forever to maintain compatibility.

Hope this helps

Duplicate documented in 802. This is NOT OUR BUG, Please direct to the Arduino team any complaints about the fact that the fix was done 3+ months ago and still isn't in a release.
