How to fix Community Connector Error in look studio? - google-apps-script

Question

I created api connector myself.
This is Code.gs file.
var cc = DataStudioApp.createCommunityConnector();
function getAuthType() {
var AuthTypes = cc.AuthType;
return cc
.newAuthTypeResponse()
.setAuthType(AuthTypes.NONE)
.build();
}
function getConfig(request) {
var config = cc.getConfig();
config.newInfo()
.setId('instructions')
.setText('Enter api url to get data , api token , username and password');
config.newTextInput()
.setId('api_url')
.setName('Enter a api url')
.setPlaceholder('https://');
config.newTextInput()
.setId('api_key')
.setName('Enter a Api Key')
.setHelpText('e.g. xxxxxxxxxxxxxxxxx');
config.newTextInput()
.setId('username')
.setName('Enter a username');
config.newTextInput()
.setId('password')
.setName('Enter a username')
.setType('password');
return config.build();
}
function getFields(request) {
var cc = DataStudioApp.createCommunityConnector();
var fields = cc.getFields();
var types = cc.FieldType;
var aggregations = cc.AggregationType;
fields.newDimension()
.setId('username')
.setType(types.TEXT);
fields.newMetric()
.setId('version')
.setType(types.NUMBER);
fields.newDimension()
.setId('address')
.setType(types.TEXT);
return fields;
}
function getSchema(request) {
var fields = getFields(request).build();
return { schema: fields };
}
function responseToRows(requestedFields, response) {
// Transform parsed data and filter for requested fields
return response.map(function(data) {
var row = [];
requestedFields.asArray().forEach(function (field) {
switch (field.getId()) {
case 'username':
return row.push(data.result.user.createdByName);
case 'version':
return row.push(data.result.user.version);
case 'address':
return row.push(data.result.user.address);
default:
return row.push('');
}
});
return { values: row };
});
}
function getData(request) {
var requestedFieldIds = request.fields.map(function(field) {
return field.name;
});
var requestedFields = getFields().forIds(requestedFieldIds);
// Fetch and parse data from API
const API_KEY = request.configParams.api_key;
var url = request.configParams.api_url;
var options = {
'method' : 'post',
'contentType': 'application/json',
"headers":{ "api-key": API_KEY },
"payload": "{username:\""+request.configParams.username+"\", password: \""+request.configParams.password+"\"}",
'muteHttpExceptions': true
};
var response = UrlFetchApp.fetch(url, options);
var parsedResponse = JSON.parse(response);
var rows = responseToRows(requestedFields, parsedResponse);
return {
schema: requestedFields.build(),
rows: rows
};
}
data from api in postman.

In the Apps Script development environment, Clicked on Deploy > Test deployments to open the Test deployments dialog.
To load your connector in Looker Studio, replace the <HEAD_DEPLOYMENT_ID> placeholder in the following link with your connector's Head Deployment ID and follow the link in your browser:
