Error code -1

I have the Sparkfun pressure sensor BMP384 and I’ve connected it to my arduino uno. I’m using the “Example1_BasicReadingsI2C” example file with some edits and it’s giving me the error -1. What does that error mean, and how can I fix it? Here’s the code I’m using:

#include <Wire.h>
#include "SparkFunBMP384.h"

// Create a new sensor object
BMP384 pressureSensor;

// I2C address selection
uint8_t i2cAddress = BMP384_I2C_ADDRESS_DEFAULT; // 0x77
// uint8_t i2cAddress = BMP384_I2C_ADDRESS_SECONDARY; // 0x76

void setup()
{
    // Start serial
    Serial.begin(9600);
    Serial.println("BMP384 Example1 begin!");

    // Initialize the I2C library
    Wire.begin();

    // Check if sensor is connected and initialize
    // Address is optional (defaults to 0x77)
//    while(pressureSensor.beginI2C(i2cAddress) != BMP3_OK)
//    {
//        // Not connected, inform user
//        Serial.println("Error: BMP384 not connected, check wiring and I2C address!");
//
//        // Wait a bit to see if connection is established
//        delay(1000);
//    }

    Serial.println("BMP384 connected!");
}

void loop()
{
    // Get measurements from the sensor
    bmp3_data data;
    int8_t err = pressureSensor.getSensorData(&data);

    // Check whether data was acquired successfully
    if(err == BMP3_OK)
   // while()
    {
        // Acquisistion succeeded, print temperature and pressure
        Serial.print("Temperature (C): ");
        Serial.print(data.temperature);
        Serial.print("\t\t");
        Serial.print("Pressure (Pa): ");
        Serial.println(data.pressure);
    }
    else
    {
        // Acquisition failed, most likely a communication error (code -2)
        Serial.print("Error getting data from sensor! Error code: ");
        Serial.println(err);
    }

    // Only print every second
    delay(1000);
}

Ensure that you are using the correct version of the Sparkfun BMP384 liybrary that is compatible with your hardware and Arduino environment.
