Hi, I´m new in Arduino and progrmaing. During the compilation in arduino ide stop compilation with error "narrowing conversion of '-1' from 'int' to 'uint8_t' {aka 'unsigned char'} [-Wnarrowing]"

Error refers to line 193 in McLightning.ino where is this command : "uint8_t strIndex[] = {0, -1};"

Original error text : McLighting.ino: In function 'String getValue(String, char, uint8_t)': McLighting:193:30: error: narrowing conversion of '-1' from 'int' to 'uint8_t' {aka 'unsigned char'} [-Wnarrowing] 193 | uint8_t strIndex[] = {0, -1};

Problem is with -1, but i´m not able to solve this problem.

Version of Arduino IDE is 1.8.15 Arduino board is NODE MCU 1.0 (ESP-12E) I use this modified version for RGBW led strip. Original MCLight Works properly.

I can not reproduce. Please check the version of your libraries.
