Code error- conversion from const char to char

Hi
I want to display image on 1.8 lcd TFT LCD module using ESP32 module below is the code I have used:

<#include <Adafruit_GFX.h>    // include Adafruit graphics library
#include <Adafruit_ST7735.h> // include Adafruit ST7735 display library
#include <SPI.h>             // include Arduino SPI library
#include <SD.h>              // include Arduino SD library
 
// define ST7735 TFT display connections
#define TFT_RST  5   // reset line (optional, pass -1 if not used)
#define TFT_CS   6   // chip select line
#define TFT_DC   7   // data/command line
 
#define button   2  // button pin
 
// initialize Adafruit ST7735 TFT library
Adafruit_ST7735 tft = Adafruit_ST7735(TFT_CS, TFT_DC, TFT_RST);
 
void setup(void) {
  Serial.begin(9600);
 
  pinMode(TFT_CS, OUTPUT);
  digitalWrite(TFT_CS, HIGH);
  pinMode(button, INPUT_PULLUP);
 
  // initialize ST7735S TFT display
  tft.initR(INITR_BLACKTAB);
 
  tft.fillScreen(ST77XX_BLUE);
 
  Serial.print("Initializing SD card...");
  if (!SD.begin()) {
    Serial.println("failed!");
    while(1);  // stay here
  }
  Serial.println("OK!");
 
  File root = SD.open("/");  // open SD card main root
  printDirectory(root, 0);   // print all files names and sizes
  root.close();              // close the opened root
 
}
 
void loop() {
  File root = SD.open("/");  // open SD card main root
 
  while (true) {
    File entry =  root.openNextFile();  // open file
 
    if (! entry) {

      root.close();

    }
 
    uint8_t nameSize = String(entry.name()).length();  // get file name size
    String str1 = String(entry.name()).substring( nameSize - 4 );  // save the last 4 characters (file extension)

  }
}

I'm getting errors is below

please help me, how to fix this error

thank you for your time

Your post was MOVED to its current location as it is more suitable.

I can't test it but see if the below change will fix it

void bmpDraw(char *filename, uint8_t x, uint16_t y) {

to

void bmpDraw(const char *filename, uint8_t x, uint16_t y) {

Thank you for your response, error was cleared after putting your solution in code but on lcd NO image displayed
in terminal something else is getting I have checked in code also there is no serial print is wrote like "Rebooting.." which as shown in terminal

Thank you for your time.

Aren’t you supposed to pass reference since File is inherited from Stream?
