I came across this issue when getting response from custom connector in PowerApps. I had gone through numerous community forum and tutorial guide on getting response data from custom connector. Hope someone would able to shed some light for me on this.
The issue I faced:
1. Kept getting True as the response from the custom connector, below is the custom connector I used.
ClearCollect(testData, CustomTrigger.Run("pending", 20, 0))

2. Unable to use CustomConnector.Run(<param>).applicant
UpdateContext({applicant: CustomTrigger.Run("pending", 20, 0).applicant})
How to re-create the situation that I faced:
1. I follow the exact steps in the following tutorial as a start (Microsoft) register-and-use-custom-apis-in-powerapps. However, I failed to get the response correctly.
3. I continue my search on the Internet and I managed to find this sergeluca.wordpress.com blog. Still, I can't get the response correctly.
Result that I'm looking for:
1. My collection is filled with the data that I wish to get from the response
{
data: [{
application: "20190331",
applicant: "John",
courseName: "Learn to be a better person",
dateStart: "2019-04-12T00:00:00.0000000",
dateEnd: "2019-04-15T00:00:00.0000000",
syllabus: [{
syllabusName: "Speak better"
}, {
syllabusName: "Listen better"
}]
}]
}Thanks
