Convert Link ID from N8N not working

amp1enator · September 20, 2022, 2:39pm

Hi,

I am using the Seatable Node in N8N to get some tables automatically exported to a csv.

Inside the node of N8N (self hosted) it is possible to activate the Option “Convert Link ID”:

But the result is an completely empty column. When the option is deactivated I am getting the IDs.

As far as I see N8N is using the right command (Line 290):

n8n-io/n8n/blob/master/packages/nodes-base/nodes/SeaTable/RowDescription.ts

import type { INodeProperties } from 'n8n-workflow';

export const rowOperations: INodeProperties[] = [
	{
		displayName: 'Operation',
		name: 'operation',
		type: 'options',
		noDataExpression: true,
		options: [
			{
				name: 'Create',
				value: 'create',
				description: 'Create a row',
				action: 'Create a row',
			},
			{
				name: 'Delete',
				value: 'delete',
				description: 'Delete a row',
				action: 'Delete a row',

This file has been truncated. show original

Does anybody has an idea how to solve this and get the text instead of the ID?

Thanks!

I’ve also recently had this issue. I have multiple columns with links and needed to solve it by having extra seatable nodes querying the ressources and merging them back together.
It was quite a painful and long process for something that I expected to be done by that option, actually.

Just a quick taste:

The subworkflows query each resource in turn, and in the end I assemble the data.

let objekt = $items("get Objekt")[0].json;

objekt["Wohnungseinheiten"] = $items("Assemble Wohnungseinheiten").map(item => item.json);
objekt["Garage / Stellplätze"] = $items("Assemble Garage / Stellplätze").map(item => item.json);
objekt["Grundrisse"] = $items("Assemble Grundrisse").map(item => item.json);

return objekt;

Maybe you can use a similar approach until this is fixed!

Right now I don’t have a system to reproduce this at hand, but it sounds to me now with two confirmations that it should be reported upstream in the N8N issue tracker:

or alternatively in the community forums:

https://community.n8n.io/

IIRC from SeaTable API use, the link / table relation can flip depending in which table the link was created. Perhaps it’s just an off-by-one error looking up the ID in the wrong table and then getting empty results, but as written, I can not reproduce this right now, sorry.

Thank you.
@Markus: Great workaround, but I think it will get messy to fast for me…

@Tom: Thanks. Then I am assuming that the Code I mentioned is basically correct and the problem must be somewhere else. I´ve made an Issue for that in Github: Seatable Node: Convert Link ID not working · Issue #4155 · n8n-io/n8n · GitHub

FYI: The solution for this is currently waiting in a push request.

Can you update here when it’s through? I might have to adjust my workaround

Yes! It works. I found time now to apply the N8N Update and test ist. Works very well.
