NS8-N8N App ready, with a few validation issues

App
1

n8n.io is a Workflow automation too for technical people.

Serverd the same functions as Make/integromat and zapier, selfhosted on your server environment.

The module can be found here: compgeniuses/ns8-n8n: Nethserver 8 Module for n8nio (github.com)

After installing the module and running it into my server, I am getting a weired validation output error.

image697Ă—508 14.6 KB

JSON Schema output validation aborted at step /home/n8n1/.config/actions/get-configuration/validate-output.json: JSON unmarshal error: unexpected end of JSON input. Input data: []

I have since tried modifying the validation output, removed it, changed it, but the error seems to persist.

One of the build worflows fails here:

Invalid workflow file: .github/workflows/build-apidoc.yml#L11
The workflow is not valid. .github/workflows/build-apidoc.yml (Line: 11, Col: 3): Error calling workflow 'NethServer/ns8-github-actions/.github/workflows/build-apidoc.yml@v1'. The workflow is requesting 'contents: write', but is only allowed 'contents: read'.

I am not sure if its a windows thing or what… also tried to resolve this.

Am building on windows, using VScode,

Anyone to assist with this?

2

can you check (console.log… maybe) what is the input data? Empty?
Does “show more” give additional info?

On the url, what is the leading f for?

3

the leading f is definetely not supposed to be there, thank you…
i dont think it could be the cause of the error, since 2 modules i am working on seem to be having that same error.

Show more does not give any more error than what is shared.

4

Do not know a thing of what that script supposed to do, know a reasonable amount of Python :slight_smile:

That leading f can be to compose a formatted string in which the values of variables in {curly brackets} are expanded:

image

If in this snippet of the script the value if the item with the key url in de dictionary data literally should be the string 'http://127.0.0.1:{os.environ["TCP_PORT"]}' then the leading f should not be there;
However: if value of url should contain value of (the variable) os.environ["TCP_PORT"] the f needs to be there…

let me re-look on the same then…

running chmod and configure the host details, does not get effected, and therefore fails to initiate the module.
getting the config details afterwards, shows no config.

where did things go wrong, and any idea on solving this weired issue.

8

well no offense but I do love to understand things with context so I need to know what you did, please follow the template I gave

it is workable from your code I only made executable the get-configure/20read file, check in your code but like I already stated any action must be executable except the json schema validator

None taken

Loggein to the server(user rocky)
su root, and ran these commands

ran
ls /home/n8n2/.config/actions/get-configuration/ -la

to confirm the files actually do exist.
then i ran

chmod a+x /home/n8n2/.config/actions/get-configuration/20read

and ls again.

ran below command to get configured items
api-cli run module/n8n2/get-configuration

since nothing is configured,

I decided to do the configuration

Now whats more curious is, Why would that file not have write permissions, from the initial code on repo,

Never ever use windows for coding…macos eventually but you have better for cheaper : Linux

I am starting to see some success

[root@ns8 n8n2]# api-cli run module/n8n2/get-configuration
Warning: using user "cluster" credentials from the environment
{"host": "n8n.bybiz.link", "http2https": true, "lets_encrypt": false}
[root@ns8 n8n2]#

these are the kinds of errors that can dim someone’s confidence…

let me push an update fixing some errors i have discoverd, then if you could kindly,
just PR the module with permission fixes afterwards,

that would help.

I have even downloaded a vscode extension that promises to resolve file write permission issues…

I wonder if github codespaces can solve…

Use WSL (Windows Subsystem for Linux) and edit your code with VS-Code on windows with remote access to WSL. It’s impossible to write scripts for Linux on a NTFS or FAT filesystem due to a mismatch in file- attributes and -permissions.

EDIT:
now also available in the Microsoft Store

everything seems to work fine now,

the only problem is now bad gateway.

How do i troubleshoot for bad gateway in module

while its possible to run the commands on wsl for vscode, its not possible for these changes to be visible to the vscode env on windows

However the vscode codespaces on github, seems to notice the changes, let me see if it works once the file competes to build

edit: nope it did not work
edit2, actually seems it worked…

Now need to figure out bad gateway

did you try it?
Over here it woks as a charm, clone of your repo in WSL editing with VS-code on Windows.

try modify the permission and see if it appears on source control
something seems different with your setup…
