Add to Marketo Campaign function in MSD throws an error
Hi all,
we have an issue with Add to Marketo Campaign feature in Microsoft Dynamics CRM (Cloud/v9). The feature is there, installed, all good. It also works in our dev CRM view (by the view I mean this). But in the production view, the function returns an error when called. See the log in the picture below:

Any ideas what could go wrong and how to fix it? I am still waiting for support for the reply and our CRM admin also doesn't know how to help.
Thank you,
Matjaž
