Description

Calling the method submitStreamingToolOutput crashes with following error at Serialization level:

java.lang.IllegalStateException: Serializing collections of different element types is not yet supported. Selected serializers: [kotlin.collections.ArrayList, kotlin.Boolean]

Steps to Reproduce

Just compute tool outputs locally and submit the streamed result with Runs.submitStreamingToolOutput That makes the kotlinx.serialization library to complain with the IllegalStateException mentioned before
