I've been trying to fix the following issue for the past two days. I want to create a user and after that return a list as shown below:
exports.createUser = functions.https.onCall((data,context) => {
try {
admin.auth().createUser({
email: "kevin3928@gmail.com"
password: "a3tbmz"
}).then((arg) => {
// a) if I return a variable here it doesn't work
});
// b) if I return a variable here it works
}
});
Returning a variable using method b) it works but I need to return the variable using method a). I can't use async and await because I will receive the following error:
error Parsing error: Unexpected token =>
✖ 1 problem (1 error, 0 warnings)
I appreciate it if someone can help me with this, I spent the entire weekend trying to solve this...
You need to return a value from the top-level code of your function, otherwise Cloud Functions may/will terminate your code before the asynchronous operation has completed.
exports.createUser = functions.https.onCall((data,context) => {
try {
return admin.auth().createUser({
email: "kevin3928@gmail.com"
password: "a3tbmz"
}).then((arg) => {
return "result";
}).catch((err) => {
return err;
});
}
});
Also see the second code snippet in the documentation on sending back the result, which does something similar.
try
let userCreated = false
exports.createUser = functions.https.onCall((data,context) => {
try {
admin.auth().createUser({
email: "kevin3928@gmail.com"
password: "a3tbmz"
})
userCreated = true
if(userCreated){
return // the object you wanted to return
}
} catch(err){
throw new Error(err)
}
});
