Retrofit API must not have replace block

I want to get data from API but get this error Here is an example of the url with coursesID params as 5012: https://dth.cohota.com/api/v1/calendar_events/?all_events=true&type=assignment&context_codes[]=course_5012

java.lang.IllegalArgumentException: URL query string "all_events=true&type=assignment&context_codes[]=course_{courseId}" must not have replace block. For dynamic query parameters use @Query.

And here is my code

 @GET("calendar_events/?all_events=true&type=assignment&context_codes[]=course_{courseId}")
    fun getCourseWithSyllabus(@Query("courseId") courseId: Long): Call<Course>

According to the official docs, I must use @Query, and i'm using it, but i also get the error. Thank you for your replies.

The error means that you can only have hardcoded query params i.e. the stuff after ?. For dynamic query params, use something like

@Query("context_codes[]") contextCodes

and supply a value like "course_$courseId" as its value.

You can examine Retrofit source to learn where the exception comes from in detail.
