Studio crashes retrieving thread ran in network mode with non JSON text output of tool call

I have tools that return string content which is not JSON. It is working well with direct agent execution, but fails when this same agent were called from another using Agent.network(). problematic message: 
[{"type":"tool-result","toolCallId":"tooluse_qUaoIDGzSZSEf9aKUiGT8w","toolName":"gitlabRestTool","result":"id: 130801... some text"}]
[{"type":"tool-result","toolCallId":"tooluse_qUaoIDGzSZSEf9aKUiGT8w","toolName":"gitlabRestTool","result":"id: 130801... some text"}]
