Node-red-contrib-advanced-ftp Access rights problem?

[struland]

Hello,
In a node-contrib-advanced-ftp node I try to list a directory with workingDir parameter set.

If I try it with workingDir = /sdcard the message is "Error: No such file or directory."

If I try it for example with workingDir = /workspace, the result is as expected. So the ftp-node seems to work fine.

The command "LIST" on the root directory shows me, that there is a directory named sdcard.

But I can not do a LIST command with "workingDir = /sdcard".

Could that be some access rights problem?
With FileZilla everything works. I can see the sdcard directory.
Please help me understand. What did I miss?

What are the ownership and access rights of the two directories?

[struland]

This is what I get with ls -al

UN65HSXXM01000535 admin@UV4:/mnt$ ls -al
drwxrwxrwt    8 root     root           160 Feb 25 10:41 .
drwxr-xr-x   17 root     root          4096 Jan 20  2020 ..

UN65HSXXM01000535 admin@UV4:/mnt/data/hmi/qthmi/deploy$ ls -al
........
drwxr-sr-x    4 root     data          4096 Mar 16  2021 workspace

With FileZilla I can get into the sdcard folder to updload, delete, rename.

[Colin]

What does root directory LIST show you for workspace?

Does the list safe for /sdcard show anything?

[struland]

This is LIST SAFE with the root directory.

The difference is the group.
workspace has 20001
sdcard has 10000

Under rights there is a "r" for everyone. So to my understanding, ftp should be able to read the "/sdcard" directory.

But it does not.

[struland]

Fortunatly I can get the file I wanted in the first place.

So when I inject:

msg.filename = /sdcard/IoT_init.json
msg.localFilename = /home/pi/IoT_init.json

that returns

"GET operation successful. /home/pi/IoT_init.json"

So I am happy.

I do not need the list feature in my workflow, anyway.
