Parameter type must not include a type variable or wildcard: java.util.Map<java.lang.String, ?>

[jikun2008]

@POST("/driver/login")
suspend fun login(@Body param:Map<String,Any>): Result<String>

ex:
{ var param= mapOf( "password" to "123123", "phone" to "123456789") service.login(param) }

use Map<String,Any> when use it case Throwable
throwabel is < java.lang.IllegalArgumentException: Parameter type must not include a type variable or wildcard: java.util.Map<java.lang.String, ?> (parameter #1) >

For now you should be able to add @JvmSuppressWildcard to the parameter to work around the issue. I'll see about relaxing the restrictions.

*@JvmSuppressWildcards

[hackaprende]

The error is still present on version com.squareup.retrofit2:retrofit:2.11.0

The solution is still the same, adding
@JvmSuppressWildcards

Just below the
@get or @post or any http method, example:

@POST(MY_URL)
@JvmSuppressWildcards
suspend fun makeRequest(@Body myList: List<MyModel>): MyResponse
