I found a similar discussion and a closed issue that might help address your problem.

1. How to pass sys.files uploaded by the user in the starting node to the LLM in the workflow? - This discussion addresses the issue of using sys.files in a workflow node after selecting the vision model gpt-4-turbo and enabling the vision switch. It suggests that additional configurations might be required to pass user-uploaded files to the LLM in the workflow ^[1].

2. The variable "sys.files" cannot be obtained in other nodes of the workflow. - This closed issue provides a workaround for accessing sys.files in intermediate nodes. It involves using the getNodeOutputVars function to ensure that sys.files is included in the output variables of intermediate nodes ^[2].

To address your issue, ensure that the isShowVisionConfig condition is true for the vision configuration, including sys.files, to be available. This is controlled by the following code:

const isShowVisionConfig = !!currModel?.features?.includes(ModelFeatureEnum.vision);

Make sure isShowVisionConfig is set to true in your configuration to enable the vision-related settings ^[3][4].

Additionally, ensure that the image upload function is enabled in the 'Features' section in the upper right corner of the application orchestration page. The workflow should be configured to handle file variables properly by fetching files from the variable pool using the _fetch_files method and converting tool messages to include files using the _convert_tool_messages method ^[5][6].

By following these steps, you should be able to use sys.files in your workflow nodes.
