[ 41874][E][Wire.cpp:499] requestFrom(): i2cWriteReadNonStop returned Error -1
I am using altimeter sensor, MPL3115A2 for measuring the height, but I get the above error for output. Can anyone explained to me what is this error and how to solve this problem? I worry that the error will affect the height reading of the sensor.

Code:
#include <Wire.h>
#include <Adafruit_MPL3115A2.h>
Adafruit_MPL3115A2 baro = Adafruit_MPL3115A2();
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.println(“\n\n========= Height of Flying Drone =========”);
if (! baro.begin())
{
Serial.println(“Invalid Input!!”);
return;
}
float altm = baro.getAltitude();
Serial.print(altm);
Serial.print(" meters\n");
delay(1000);
}
This is my code.
I used the library, Adafruit_MPL3115A2.
FYI, the board that I am using is ESP32 dev board, and platformio
