Unrecognized node type: @n8n/n8n-nodes-langchain.vectorStoreSupabase

[Emin_Laz]

I’m not sure why I’m getting this, didn’t happen before

Do share you workflow as a json using the file upload option in this reply session. So that i can look further. Basically the issue may arise from the improper use of nodes. But still iwould like to see in detail.

I don’t see any upload file button

One thing that I see is that, the workflow works perfectly fine when your testing it, but when it’s active and you chat with it you get this:

I’m certain, that this is happening because I once downloaded this community package: @n8n/n8n-nodes-langchain, my bad because, first it’s a very old community package and second, my workflow is hosted on railway and as far as I know you can’t download any community packages when it’s not locally hosted

@King_Samuel_David as you know, I redeployed n8n, but I still get this, maybe you have a solution again?

So you see this icon on top right? ( </> ) . This is where you will have to copy the code of your workflow … the json code…
and secondly the issue isnt due to the package. I mean for now thats not a solid reason untill i have checked and confirmed it myself. So do share this so i could provide you with the solution. Also i will be able to solve the solution more quickly if you additionally send a screen recording video of you error and send it to me here or via email so that i can understand it well and answer you here… hope this works… Thank you

Whats ure actual setup? Do you have workers? webhook nodes?

You can also try delete the superbase u have in the flow, and add again, maybe it calling an old module?

if u do this, I can test on my side for you too,

When u click the code icon, just hit paste to avoid issue etc.

Happy to help work out what’s causing this.

I can’t upload the whole things it has to many characters

[Emin_Laz]

Per mail if it’s okay, can’t send it here, because it has to many characters

[Emin_Laz]

I can’t upload the whole things it has to many characters

[King_Samuel_David]

ah okay, id like to test on my side, see if same issue. could u make a simpler flow with just the main issue part. is it same on other workflow?

[Emin_Laz]

So I found out, that the workflow itself is okay, but my account isn’t - it’s actually the community node that I shouldn’t have downloaded

If you ask how I know - I created another “account” on railway and copied the whole workflow over there, setted up the credentials and made it active and I could chat with it with no problems.

I’m not sure what I can do, but hope that the next n8n update fixes the account on it’s own.
