Currently reading of Flows is not supported in the library, it is actually broken in the Salesforce API this library wraps. I'm waiting for that to be fixed and I will update the library. Here is the duplicate issue. #26.

Hi ,

Im Having the same issue with workflow rules , although i have used the method for workflow field updates and validation rules and it works just fine , any thoughts ?

[afawcett]

Have you seen this example?

@afawcett I'm seeing this exact behavior on RemoteSiteSettings. It looks like readMetadata for RSS just returns null no matter what. Have you seen this too?

(I've confirmed behavior in JSForce and Postman raw posts as well)

[afawcett]

@triestelaporte if you use listMetadata or the equiv from within Developer Workbench what Metadata Fullname is assocaited to the Remote Site?

I was able to fix this by specifying the full name of the RemoteSiteSetting.

MetadataService.RemoteSiteSetting wfa = (MetadataService.RemoteSiteSetting) service.readMetadata('RemoteSiteSetting',
                new String[]{
                        '<REMOTESITESETTING FULLNAME>'
                }).getRecords()[0];

        System.debug(wfa.url);

Thanks for sharing @Dobermaxx99

So, I'm assuming that still doesn't work? Here's what I'm passing:

MetadataService.Flow flowResult = (MetadataService.Flow) mdService.readMetadata('Flow', new List<String>{'<NAME OF FLOW>'}).getRecords()[0];

All values (actionCalls, decisions, etc.) still return as "null". When I make a call using the REST Explorer, however, it returns that data just fine. It is clear that the data is there. Why isn't it returning using the syntax above?
