JSON syntax for GET/tasks with optional fields

Same issue here. Using the same field parameter specified in the API, my returned tasks include *none* of the fields listed. 

Scribe Connector

In your example curl, you've included some generic example keys for metadata. Try replacing the URL portion of your curl with:

https://www.wrike.com/api/v4/tasks?createdDate={"start":"2019-07-30T15:40:55Z"}&dueDate={"start":"2019-06-30"}&sortOrder=Desc&sortField=CreatedDate&scheduledDate={"start":"2019-06-30","end":"2019-08-31"}&updatedDate={"start":"2019-07-30T15:40:55Z","end":"2019-08-01T15:40:55Z"}&fields=["authorIds","briefDescription","dependencyIds","attachmentCount","description","customFields","metadata","responsibleIds","superParentIds","recurrent","hasAttachments","parentIds","sharedIds","superTaskIds","subTaskIds"]&descendants=true&startDate={"end":"2019-08-31T18:40:55"}&status=Active

This is an exact copy of your example, with just the metadata parameter removed, so it assumes you are intentionally filtering the tasks returned by including all of these filter parameters.

Thanks, Laura,

Here is the JSON that I came up with to define these filters for the Scribe Online solution I am working with. To use the filter parameters in Scribe, I use the statement below, where the "Id" of the custom field is: "IEACPQK2JUAA7RR6" and the value I'm filtering for is "Ultra Complex".
