I want to delete by facebook provider user in my firebase authentication using this question in my nodeJs. But somehow i getting error that getUserByProviderUid is not a function. I attached the error message below.
Here is code
exports.deleteUserData = functions.https.onRequest(async (req,
res) => {
try {
const signedRequest = req.body.signed_request;
console.log('signRewues',signedRequest)
const userObj = parseSignedRequest(signedRequest,
'Facebook secret');
console.log('User Obj',userObj, userObj.user_id);
const userRecord = await
admin.auth().getUserByProviderUid("facebook.com",
userObj.user_id);
console.log('userRecord',userRecord);
await admin.auth().deleteUser(userRecord.uid);
res.json({
url: "<URL>",
confirmation_code: "<Code>",
});
} catch (e) {
console.log(e);
res.status(400).json({
message: "Bad Request",
});
}
});
function base64decode(data) {
while (data.length % 4 !== 0) {
data += "=";
}
data = data.replace(/-/g, "+").replace(/_/g, "/");
return Buffer.from(data, "base64").toString("utf-8");
};
function parseSignedRequest(signedRequest, secret) {
var encoded_data = signedRequest.split(".", 2);
// decode the data
var sig = encoded_data[0];
var json = base64decode(encoded_data[1]);
var data = JSON.parse(json);
if (!data.algorithm || data.algorithm.toUpperCase() != "HMAC-
SHA256") {
throw Error(
"Unknown algorithm: " + data.algorithm + ". Expected HMAC-
SHA256"
);
}
var expected_sig = crypto
.createHmac("sha256", secret)
.update(encoded_data[1])
.digest("base64")
.replace(/\+/g, "-")
.replace(/\//g, "_")
.replace("=", "");
if (sig !== expected_sig) {
throw Error("Invalid signature: " + sig + ". Expected " +
expected_sig);
}
return data;
}

The getUserByProviderUid() was added in version 9.5.0 of Admin SDK. You'll have to update the Admin SDK to use it. Try upgrading to latest version.
npm i firebase-admin#latest
