I am facing an issue running Google Calendar API in my spring boot project. It is an enterprise project which is running on live server
GoogleCalendarService.java
@Service
@Slf4j
public class GoogleCalenderService {
private static final List<String> SCOPES = Collections.singletonList(CalendarScopes.CALENDAR);
private static final String CREDENTIALS_FILE_PATH = "/RP_OAuth.json";
private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

private static final String APPLICATION_NAME = "Google Calendar API Java Quickstart";
private GoogleAuthorizationCodeFlow flow;
private NetHttpTransport HTTP_TRANSPORT;
public String getCredentials(String candidateEmail,String recruiterEmail,long startTimeStamp, long endTimeStamp) {
// Load client secrets.
try {
AuthorizationCodeRequestUrl authorizationUrl;
authorizationUrl = getFlow().newAuthorizationUrl()
.setRedirectUri("http://localhost:8948/Callback/"
+startTimeStamp+
"/"+endTimeStamp+
"/"+recruiterEmail+
"/"+candidateEmail
);
return authorizationUrl.build();
} catch (Exception e) {
log.error(e.getMessage());
}
return null;
}
public GoogleAuthorizationCodeFlow getFlow() {
if (flow == null) {
try {
HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
InputStream in = GoogleCalenderService.class.getResourceAsStream(CREDENTIALS_FILE_PATH);
if (in == null) {
throw new FileNotFoundException("Resource not found: " + CREDENTIALS_FILE_PATH);
}
GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
flow = new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(new FileDataStoreFactory(new java.io.File(TOKENS_DIRECTORY_PATH)))
.setAccessType("offline")
.build();
} catch (Exception e) {
log.error(e.getMessage());
}
}
return flow;
}
public String createCredentials(String code,long startTimeStamp, long endTimeStamp, String recruiterEmail,
String candidateEmail) {
try {
TokenResponse response = getFlow().newTokenRequest(code).setRedirectUri("http://localhost:8948/Callback/"
+startTimeStamp+
"/"+endTimeStamp+
"/"+recruiterEmail+
"/"+candidateEmail
)
.execute();
Credential credential = flow.createAndStoreCredential(response, "userID");
Calendar service = new Calendar.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName(APPLICATION_NAME)

new EventAttendee().setEmail(candidateEmail),
};
event.setAttendees(Arrays.asList(attendees));
EventReminder[] reminderOverrides = new EventReminder[]{
new EventReminder().setMethod("email").setMinutes(24 * 60),
new EventReminder().setMethod("popup").setMinutes(10),
};
Event.Reminders reminders = new Event.Reminders()
.setUseDefault(false)
.setOverrides(Arrays.asList(reminderOverrides));
event.setReminders(reminders);
String calendarId = "primary";
event = service.events().insert(calendarId, event).execute();
System.out.printf("Event created: %s\n", event.getHtmlLink());
return event.getHtmlLink();
} catch (IOException e) {
