Permission issues with Read/Write Node in Docker (Coolify)

[tamy.santos]

Hi @marexxxxxxx, welcome to the community!

Since you’re on version 2.1.5 and using Task Runners, a common “gotcha” is the shared filesystem . Even if you’ve set the N8N_RESTRICT_FILE_ACCESS_TO variable correctly, both the main n8n container and the task-runner container need to have the exact same volume mounted at the exact same path. If they aren’t perfectly synced, the task-runner might be trying to write to a directory that only exists in its own isolated ephemeral storage.

In Coolify, double-check that your files volume is actually attached to bothservices in your compose file.Just as a test, have you tried writing to a subdirectory within the default /home/node/.n8n/ folder? Sometimes that bypasses external mount headaches.

merging files inside a loop using binary nodes can be really tough on memory. Most people in the community find it much smoother to use ffmpeg via the Execute Command node if your Docker image supports it. It’s usually faster and less prone to crashing the workflow.

By the way, could you share how you defined the volumes for the task-runner in your compose file?

Read/Write Files from Disk node works in test but not in production

Hi everyone, I’m experiencing an odd issue with the Read/Write Files from Disk node in n8n. Here’s the situation: When I test the workflow using “Execute Node” in the editor, everything runs perfectly. The node reads files as expected. However, when I activate the workflow and use the production webhook URL, the Read/Write Files from Disk node fails to do its job. Everything else in the workflow (like other nodes or steps) works fine, but this specific node fails or returns no data. N8N versio…

Write to windows folder from within Docker n8n

I use n8n v2 hosted in a docker container. I want to write a file with the Read/Write node. The field for the file+path is: local_files/test.txt I mounted local_files in the docker-compose.yml: volumes: - ./n8n_data:/home/node/.n8n - ./n8n_files:/home/node/local_files The folder “n8n_files” exists beside the “n8n_data” folder. But try to write the file, I get the error: The file "/home/node/local_files/test.txt" is not writable.
