Unable to get access token from Mule Salesforce

Question

I am unable to get an access token when trying to get one from SalesForce. I entered a callback URL of https://localhost:8081/AppCallback. However, I get null in my browser when I print out the token. When I change the consumer key value I still get success, it doesn't seem like I'm hitting the service. Here is my configuration. I send a request to http://localhost:8081/authorize and I get back

You have successfully authorized the connector. Your access token id is:null

<http:listener-config name="HTTP_Listener_Configuration"

        <sfdc:config-with-oauth name="salesforce-oauth"

            onNoToken="EXCEPTION"

       accessTokenUrl="https://app.my.salesforce.com/services/oauth2/token"

     authorizationUrl="https://app.my.salesforce.com/services/oauth2/authorize"

            consumerKey="myConsumerKey"

            consumerSecret="33388E8E" doc:name="Salesforce (OAuth)">

            <sfdc:oauth-callback-config domain="localhost"

                localPort="8081" remotePort="8081" path="AppCallBack" />

        </sfdc:config-with-oauth>

            </http:listener>

            <sfdc:authorize immediate="TRUE" config-ref="salesforce-oauth"  display="PAGE" doc:name="Authorize at Salesforce" />

        </flow>

  <flow name="sfdctestFlow1" doc:name="readContactFlow1">

            <http:listener config-ref="HTTP_Listener_Configuration"

                path="run" doc:name="HTTP" />

            <sfdc:query config-ref="salesforce-oauth" accessTokenId="#[flowVars.OAuthAccessTokenId]"

                doc:name="Perform a query at Salesforce" query="SELECT id,lastname,lastmodifieddate from contact limit 10" />

            <foreach doc:name="For Each">

                <logger doc:name="Logger" level="INFO" message="contact: #[payload]" />

            </foreach>

            <set-payload doc:name="Set Payload to formatted output"

                value="Salesforce query returned #[payload.size()] contacts." />

            <logger doc:name="Logger" level="INFO" message="contact: #[payload]" />

        </flow>

What am I doing wrong? Why isn't the Salesforce validating and returning an access token? How am I supposed to use the callback URL?

Answer 1

The error you're facing is that your mule instance isn't connecting to the Salesforce's OAuth token provider.
