React-native – Promise using GraphRequestManager

FBGraphRequest = async (fields) => {
 const accessData = await AccessToken.getCurrentAccessToken();
 // Create a graph request asking for user information 
 return new Promise((resolve, reject) => {
 const infoRequest = new GraphRequest('/me', {
 accessToken: accessData.accessToken,
 parameters: {< br /> fields: {
 string: fields
 }
 }
 },
 (error, result) => {
 if (error) {
 console.log('Error fetching data: '+ error. toString());
 reject(error);
} else {
 resolve(result);
 }
 });

 new GraphRequestManager().addRequest(infoRequest).start();
 });
 };



 triggerGraphRequest = async () => {
 let result = await this.FBGraphRequest('id, email');
 return result;
 }

Does anyone have an example of how to use GraphRequestManager’s promise?
I got the attribute of Undefined error cannot be read in my action creator.

function graphRequest(path, params, token=undefined, version=undefined, method='GET') {
return new Promise((resolve, reject) => {
 new GraphRequestManager().addRequest(new GraphRequest(
 path,
 {
 httpMethod: method,
 version: version,
 accessToken: token
 },
 (error, result) => {
 if (error ) {
 console.log('Error fetching data: '+ error);
 reject('error making request.' + error);
} else {
 console.log ('Success fetching data:');
 console.log(result);
 resolve(result);
 }
 },
 )).start() ;
});

}

I use my action creator to call the above content

export function accounts() {
return dispatch => {
 console.log("fetching accounts!!!!!!");
 dispatch(accountsFetch());
 fbAPI.accounts().then((accounts) => {
 dispatch(accountsFetchSuccess(accounts));
 }).catch((error) = > {
 dispatch(accountsFetchFailure(error));
 })
}

}

I get “Successfully fetched data: “And the result before the error. So the API call completed successfully. The error is after getting the account in fbAPI.accounts(). Then ((account) I think it is because GraphRequestManager returns immediately instead of waiting.

I have a solution for you.
My provider looks like this:

FBGraphRequest = async (fields) => {
 const accessData = await AccessToken.getCurrentAccessToken();
 // Create a graph request asking for user information
 return new Promise((resolve, reject) => {
 const infoRequest = new GraphRequest('/me', {
 accessToken: accessData.accessToken,
 parameters: {
 fields: {
 string: fields
 }
 }
 },
 (error, result) => {
 if (error) {
 console.log('Error fetching data: '+ error.toString());
 reject(error);
} else {
 resolve(result);
 }
 });

 new GraphRequestManager().addRequest(infoRequest).start();
 });
 };



 triggerGraphRequest = async () => {
 let result = await this.FBGraphRequest('id, email');
 return result;
 }

This is great! I adapt your solution to your system.
