I’m getting the following error in some random interactions in my flow.
Failed to transform agent message: req_id: {{id}} PluginInvokeError: {“args”:{},“error_type”:“Exception”,“message”:"read llm model failed: request failed: req_id: {{id}} PluginInvokeError: {\“args\”:{\“description\”:\"1 validation error for LLMResultChunk\\nmodel\\n Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]\\n For further information visit https://errors.pydantic.dev/2.12/v/string_type\"},\“error_type\”:\“InvokeError\”,\“message\”:\"1 validation error for LLMResultChunk\\nmodel\\n Input should be a valid string [type=string_type, input_value=None, input_type=NoneType]\\n For further information visit https://errors.pydantic.dev/2.12/v/string_type\“}”}
Does anyone know why this happens and how to solve it permanently?
