Got an exception when run on web

[hnvmeta]

I got this exception when I run code on web. It works well when I run on Android.
_aiMessages.add(OpenAIChatCompletionChoiceMessageModel( content: [ OpenAIChatCompletionChoiceMessageContentItemModel.text(prompt), OpenAIChatCompletionChoiceMessageContentItemModel.fromMap( {'type': 'image_url', 'image_url': imageUri}) ], role: OpenAIChatMessageRole.user, ));
