Migration Report still warns about absolute file paths even after setting N8N_RESTRICT_FILE_ACCESS_TO

Describe the problem/error/question

Hi everyone,
I’m preparing for the upcoming n8n v2 file-access restrictions, and I noticed something that doesn’t seem to behave consistently.

In the Migration Report, nodes that use absolute paths (for example /tmp/...) are flagged with this warning:

“File Access Restrictions”

To prevent this, I added the environment variable:

N8N_RESTRICT_FILE_ACCESS_TO="/tmp/"

I expected the warning to disappear, just like what happens with other migration warnings (for example NODES_EXCLUDE, which disappears once the env variable is set).

However, even after setting N8N_RESTRICT_FILE_ACCESS_TO, the Migration Report still shows warnings for nodes using /tmp/.

So my question is:

Should the Migration Report detect that /tmp/ is explicitly allowed in the environment variable, or is this warning expected to remain even when the directory is whitelisted?

I want to make sure that in n8n v2 my workflows will not break, since many nodes temporarily write or read files in /tmp/.

What is the error message (if any)?

Migration Report warning:

File Access Restrictions - Medium
File access is now restricted to a default directory for security purposes

This warning appears even though the directory /tmp/ is explicitly included in N8N_RESTRICT_FILE_ACCESS_TO.

same ask, also want to know in Docker Compose, how to include more than more directory to exclude in this variable. Thanks

Just test, it should set like this for multiple allowed location. But same as op, the warning won’t go away

N8N_RESTRICT_FILE_ACCESS_TO=~/.n8n;/tmp

Same here, just fixed the path issue but still appears. I tried to restart the container…same result.
