aggregateMember(memberId, userId) method call producing NPE

[tylercote]

Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null

ApiClient.java line 1131 has:
reqBody = RequestBody.create("", MediaType.parse(contentType));
contentType is null here, and my IDE is also suggesting "Cannot resolve method 'create(String, MediaType)'" for okhttp3 lib.

Hopefully this context might help

Below is a stacktrace from my debugger.

It seems like adding the following dependencies forces the right version, but I am still get a null contentType exception.

implementation 'com.squareup.okhttp3:okhttp:4.10.0' implementation 'com.squareup.okhttp3:logging-interceptor:4.10.0' implementation 'com.mx:mx-platform-java:0.10.1'
