Hi there Hope you are well. I have one problem regarding the function node in the edge workflow. So, currently my edge workflow is working properly before adding the function node. I am using the string node to process the string, but as you know, it asks a lot of string nodes to process the complicated string. So I added the function node there, but it throws the timeout error and the whole edge workflow does not work. So, what is wrong? Can you please help me? Thanks. ![image](https://us1.discourse-cdn.com/flex015/uploads/getstructure/original/2X/2/2414c51b30d08262a7953858079b528622667503.png) ---

We had another user run into a similar problem last week, and it had to do with his hardware taking too long to spin up the Function Node’s sandbox environment. There is a workaround: Set the [`MAX_FLOW_RUN_TIME` environment variable](https://docs.losant.com/edge-compute/gateway-edge-agent/usage/#advanced-options) to a much higher value, like `300000` (5 minutes). This works because the script to start up the Function Node’s sandbox environment will halt after (`MAX_FLOW_RUN_TIME` / 4) milliseconds. We’re investigating this issue more but hopefully that gets you unblocked for now. ---

Hi @Dylan_Schuster Thank you for your update. So, where can I set this environment variable? Can you please let me know in details? Thanks. ---

This would go in the [script to start the GEA’s Docker container](https://docs.losant.com/edge-compute/gateway-edge-agent/usage/#running-with-environment-config). Something like … ```auto docker run -d --restart always --name docs-agent \ -e 'DEVICE_ID=' \ -e 'ACCESS_KEY=' \ -e 'ACCESS_SECRET=' \ -e 'MAX_FLOW_RUN_TIME=300000' \ -v /var/lib/losant-edge-agent/data:/data \ losant/edge-agent ``` ---

Hi @Dylan_Schuster I have one more question, so now it is working properly. But I have found another issue. So, I am using the run executable node in my edge workflow, by the way, sometimes it does not get the result. And sometimes it gets the command result properly. I can not understand why. Can you please help me in terms of this issue? Regards, ---

Sorry, but I need a lot more info before I could be of help with that request. Are there any [errors](https://docs.losant.com/workflows/workflow-metrics/#workflow-errors) being thrown in the workflow execution? What sort of configuration are you providing to the Run Executable Node - including what exactly you are executing? And whatever the script is, is it possible it could not exit with a status code or it could hang? I recommend starting a new thread for this request and providing as much information as you can.
