Fingerprint Sensor Enrollment Failing at Image Conversion Step

hey guys, I’ve successfully initialized the fingerprint sensor using UART, but when I attempt to enroll a new fingerprint, the enrollment process fails after step 2 (converting image to template). The `enrollFinger()` method returns an error code `FINGERPRINT_IMAGEMESS`.
here is my code:
“`int result = finger.enrollFinger(1); // Enroll fingerprint with ID 1
if (result == FINGERPRINT_OK) {
Serial.println(“Fingerprint enrolled!”);
} else {
Serial.print(“Enrollment failed: “);
Serial.println(result);
}
“`
I’ve tried adjusting the sensor sensitivity and checked for debris on the sensor, yet the error persists. what could be wrong?
