CloverDX Platform

Hi All,

I am new user to the clover ETL designer. I am trying to get some data from the webservice but I am getting the following error. Could you please let me know how to fix this error.

Following is the log file.

Hello, Akhil,

if I may, I have a few questions for you:

1. Are you working the whole time with the authentication token send by salesforce server during login process? If you are not, please see the example showing typical usage of salesforce api. You can find it on your welcome screen (Designer GUI → Help → Welcome → Explore Examples → Salesforce).

2. Can you please turn on debug level logging? (Run → Run Configurations… → Log level) Then post the new log here, please.

3. Can you post also your graph? This is for us being able to reproduce your issue.

Thank you in advance.

Best regards,

Hi,

I am trying to run the example mapping for salesforce, 06-ExternalInteraction-SalesforceWebServices - 06-Graph-2.grf. The same map I have renamed as SalesforceContactList.grf. Please find the XML file of the mapping.

<?xml version="1.0" encoding="UTF-8"?> <!\[CDATA\[//#CTL2

// Transforms input record into output record.
function integer transform() {
$out.0.joiner = $in.0.dtJoiner;
$out.0.sessionID = $in.0.dtSessionID;
$out.0.serverURL = $in.0.dtSessionURL;

return OK;
}

// Called during component initialization.
// function boolean init() {}

// Called during each graph run before the transform is executed. May be used to allocate and initialize resources
// required by the transform. All resources allocated within this method should be released
// by the postExecute() method.
// function void preExecute() {}

// Called only if transform() throws an exception.
// function integer transformOnError(string errorMessage, string stackTrace) {}

// Called during each graph run after the entire transform was executed. Should be used to free any resources
// allocated within the preExecute() method.
// function void postExecute() {}

// Called to return a user-defined error message when an error occurs.
// function string getMessage() {}

I ran the graph with the debug mode but both the logs looks the same.

Hi Akhil,

Thank you for all the detailed information. As you can see in JobFlowExamples this graph is just a “sub-graph” that is supposed to be executed from master JobFlow (06-ExternalInteraction-SalesforceWebServices.jbf). This particular graph expects to receive data from aforementioned JobFlow. As you can see in the log, dictionary entries that should be populated with input data are null. If you would like to run these examples, you should run this graph via the mentioned JobFlow.
