是否可以使用 public 交通方式或使用此处 API 骑自行车来创建等值线？

Question

创建一些东西

这使用 the Here API。据说可以在 Mode 中使用 public 运输和骑自行车，但是当我这样做时，我得到一个错误：

Isoline API failed with the following error: InvalidInputData

通过查看 the documentation public 交通和自行车适用于路线规划，但可能不适用于等值线。

这是相关的闪亮代码（受上述应用程序影响很大）：

    is_valid = validate_inputs(session, input$origin, input$departure, input$min, input$max, input$step)

    if(is_valid) {

        progress$status$set(message = 'Requesting...')

        departure = paste0(input$departure, ' ',input$time, ':00:00')
        range_type = switch(input$range_type, 'Time (minutes)' = 'time', 'Distance (metres)' = 'distance')
        unit = switch(input$range_type, 'Time (minutes)' = ' minutes', 'Distance (metres)' = ' metres')
        mode = switch(input$mode, 'Pedestrian' = 'pedestrian', 'Public Transport' = 'publicTransport', 'Bike' = 'bicycle', 'Car' = 'car')
        isoline_sequence = if(input$range_type == 'Time (minutes)') {
            seq(input$min, input$max, input$step) * 60 %>% sort()
        } else {
            round(seq(input$min, input$max, input$step), digits = 0) %>% sort()
        }

        layers = sapply(1:length(isoline_sequence), function(x) {
            progress$status$inc(amount = 1/length(isoline_sequence),
                                message = paste0('Processing request ', x, ' of ', length(isoline_sequence)))
            isoline(str_remove(input$origin, ' '), departure = departure, range_type = range_type,
                    range = isoline_sequence[x], mode = mode, app_id = keys$app_id, app_code = keys$app_code)
        })

任何帮助都会很棒！

截至目前，calculate Isoline API 仅支持 car、truck 和 pedestrian 传输模式。请参阅文档： https://developer.here.com/documentation/routing/topics/resource-calculate-isoline.html:

Types supported in isoline request: fastest, shortest.

TransportModes supported in isoline request: car, truck (only with type fastest), pedestrian.

Is it possible to create Isolines using public transport or cycling using the Here API?
