Non-body HTTP method cannot contain @Body

Question

Getting mentioned Error in Retrofit

 java.lang.IllegalArgumentException: Non-body HTTP method cannot contain @Body.
        for method AuthApi.fetchUser

        at $Proxy2.fetchUser(Unknown Source)
        at org.app.profile.repository.ProfileRepository$fetUser$2.invokeSuspend(ProfileRepository.kt:12)

I have set request as

@GET("fetchUser")
    suspend fun fetchUser(
        @Body request: JsonObject
    ): Response<ResProfile>

How can I solve this issue?
