Do you have questions on how to build the Ktorfit project? Feel free to ask them here.
I wrote a general overview over the components here

Hi. I wanted to ask a question regarding StringValues. I have to send an array of id's as formdata.
This is my implementation:

        val groups: StringValues = StringValuesSingleImpl(
            caseInsensitiveName = false,
            name = "groupIds",
            values = groupIds
        )

        val bodyParameters = Parameters.build {
            appendAll(groups)
        }

        val result = provider.eventApi.addGroups(
            eventId = eventId,
            authToken = authHeader.value,
            body = FormDataContent(bodyParameters)
        )

where eventId: String, groupIds: List<String>

THE API works, if I send 2 or more data inside the groupIds field. But the server get's a different format if there is only 1 value in the list. Any advice?
