To generate a personalized error on a Firebase callable cloud function, you can follow these steps:
Define your error message: Decide on the error message that you want to show to the user when the function encounters an error.
Use throw
keyword: Use the throw
keyword to throw an error in your function code. For example, you can use the following code:
throw new functions.https.HttpsError('invalid-argument', 'Invalid argument supplied');
This code throws an error with a status code of invalid-argument
and an error message of Invalid argument supplied
.
catch
block of your function call code. For example, you can use the following code: functions.httpsCallable('myFunctionName')({ ... })
.then(result => { ... })
.catch(error => {
console.error(error);
console.log(error.code, error.message, error.details);
});
In this code, the catch
block handles the error and logs the error code, message, and details to the console.
By following these steps, you can generate a personalized error message for your Firebase callable cloud function.
