Hi!
I found duplication of the ArduinoJson library.
Original library: https://platformio.org/lib/show/64/ArduinoJson
Duplicate library: https://platformio.org/lib/show/12209/ArduinoJson
Best regards
The duplicate on is uploaded by user mertmechanic as seen in the install tab and might actually be a modification of the original library, which is fine to upload and use. Haven’t compared the internal differences though.
