Error during PlatformIO build for Portenta H7

[mrccwolf]

Environment

• Arduino Portenta h7 m7
• Platform: ststm32
• IDE: Platform IO (VSCode)
• Occurs with both ArduinoJson 6.18.5 and 6.19.2 (assumed same for all other versions)
• Also happening in a fresh install of the Arduino IDE 2.x as well

Here is the error, it happens during import.

Can anyone replicate?

[mrccwolf]

This is resolved, this was difficult to find since both IDE were not referencing the correct line number.

incorrect code:

char* type = doc["type"];

corrected

const char* type = doc["type"];
