LLM Playground Consistent Error In Logfire Dashboard

[c2keesey]

Description

Every time I try to continue a conversation in the playground, I get this error even though the original run works fine:

Error
status_code: 400, model_name: claude-opus-4-5, body: {'type': 'error', 'error': {'type': 'invalid_request_error', 'message': 'messages.0.content.1: unexpected `tool_use_id` found in `tool_result` blocks: toolu_015wrtzPiFUKyidNpXirV2Nv.
