Crash using streamed API to submit tool outputs

[davidgarciaanton]

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

Environment

• openai-kotlin version: 4.0.1
• Kotlin version: 2.1.10
• OS: Mac

Additional Info

There's also an open issue in YouTrack for the root cause

I submitted the same issue without having seen yours, with some extra details.

#422

Not sure if we should merge both.

[davidgarciaanton]

Don't know. Actually, even affecting the same method it seems that we had different problems. I had some problem regarding the serialization of mixed types (the list of tool outputs, and a boolean).

In contrast I didn't see the crash you mentioned. And that makes me wonder why could it be happening. Apparently we're using very similar setup (versions and OS).

Which ktor client engine choice did you make? I choose okhttp (Also, I choose version 3.0.0 of ktor dependency)
