Two custom methods/endpoints using loopBack, one works, the other gives a 401 - react-native

Question

I created two custom endpoints with Loopback.
Account.deleteAllHearingTests = function (req, callback) {
console.log('here comes the req to delete all hearing tests', req);
Account.findById(req.accessToken.userId)
.then(account => {
if (!account) {
throw new Error('cannot find user');
}
return app.models.HearingTest.updateAll({ accountId: account.id }, { isDeleted: new Date() });
})
.then(() => {
callback(null);
})
.catch(error => {
callback(error);
})
}
Account.remoteMethod(
'deleteAllHearingTests', {
http: {
path: '/clearHearingTests',
verb: 'post'
},
accepts: [
{ arg: 'req', type: 'object', http: { source: 'req' } }
],
returns: {}
}
);
the second one looks like this.
Account.deleteSingleHearingTest = function (req, callback) {
// console.log('accounts.js: deleteSingleHearingTest: are we being reached????', req)
Account.findById(req.accessToken.userId)
.then(account => {
if (!account) {
throw new Error('Cannot find user');
}
console.log('account.js: deleteSingleHearingTest: req.body.hearingTestId N: ', req.body.hearingTestId);
return app.models.HearingTest.updateAll({ accountId: account.id, id: req.body.hearingTestId }, { isDeleted: new Date() });
})
.then(() => {
callback(null);
})
.catch(error => {
callback(error);
});
}
Account.remoteMethod(
'deleteSingleHearingTest', {
http: {
path: '/deleteSingleHearingTest',
verb: 'post'
},
accepts: [
{ arg: 'req', type: 'object', description: 'removes a single hearing test', http: { source: 'req' } }
],
description: 'this is the end point for a single delete',
returns: {}
}
);
};
The first custom method returns a 401 status response when I make the initial fetch. The second returns a 200.
Inside my actions file the first method is called with something that looks like this:
export function deleteAllHearingTests() {
return (dispatch, getState) => {
let state = getState();
if (!state.user || !state.user.accessToken || !state.user.accessToken.id || !state.user.accessToken.userId) {
console.debug('deleteAllHearingTests', state.user);
// TODO: ERROR
return;
}
fetch(SERVERCONFIG.BASEURL + '/api/Accounts/clearHearingTests?access_token=' + state.user.accessToken.id, {
method: 'POST',
headers: SERVERCONFIG.HEADERS
})
.then(response => {
console.log('here is your response', response);
if (response.status !== 200) {
throw new Error('Something is wrong');
}
return response.json()
})
the second method is called with
export const deleteSingleHearingTest = (hearingTestNumber) => {
return (dispatch, getState) => {
let state = getState();
if (!state.user || !state.user.accessToken || !state.user.accessToken.id || !state.user.accessToken.userId) {
console.debug('writeTestResult', state.user);
// TODO: ERROR
return;
}
console.log('single delete ', SERVERCONFIG.BASEURL + '/api/Accounts/deleteSingleHearingTest?access_token=' + state.user.accessToken.id)
fetch(SERVERCONFIG.BASEURL + '/api/Accounts/deleteSingleHearingTest?access_token=' + state.user.accessToken.id, {
method: 'POST',
headers: SERVERCONFIG.HEADERS,
body: JSON.stringify({ "hearingTestId": hearingTestNumber })
})
.then(response => {
console.log('getting response from initial fetch inside deleteSingleReqport', response);
They are nearly identical, however, one works..the other fails. What are some possible causes for the 401?

Answer 1

Did you try to call those methods with external tool like a postman, so you would exactly know if you don't miss access_token or something else? Also, when you compare code from one function and another, you can see that you are colling the updateAll with different arguments. It's hard to say without original code, but maybe the issue is there? Compare below:
return app.models.HearingTest.updateAll(
{ accountId: account.id },
{ isDeleted: new Date() });
return app.models.HearingTest.updateAll(
{ accountId: account.id, id: req.body.hearingTestId },
{ isDeleted: new Date() });
Additionally, in fetch method they are also diffferences, you are missing in one case the below:
body: JSON.stringify({ "hearingTestId": hearingTestNumber })
What you could also do to debug and to provide more data is to run server in debug mode by calling:
export DEBUG=*; npm start
