Hi,
I built a custom connector with a `NewLead` trigger and a `CreateLead` action. Both have an input value called `channel_id`. The `channel_id` should be chosen from a dynamic dropdown that makes a GET request via the `GetChannels` action.

Everything is set up, and the `GetChannels` action is fetching the list of channels correctly when I test it in isolation, but when I am testing the dynamic dropdown for the `channel_id` input, the `GetChannels` request is failing, and shows this error message in the dropdown:

The dynamic invocation request failed with error: Unexpected error occurred when calling the ApiHubsRuntime API: 'System.InvalidOperationException: Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects.

What is this error message referring to?

My request headers are these:

"Accept": "application/json",
"OData-MaxVersion": 4,
"OData-Version": 4,
"If-None-Match": "null",
"Content-Type": "text/plain"
}

My response headers are these:
