Hey @Louis-pa,

We have created an internal ticket to look into this which we will be tracking as "GHC-491"

Hey @Louis-pa,

I have just tried to reproduce this but I am able to delete nodes, Can you provide some more information.

1) Which template are you using? 2) Which version of n8n are you running? 3) Which browser are you using? 4) Are you using the new canvas?

Hello, I'm using self-hosted version of n8n. I have the bug with all templates I'm using v 1.69.0 :

{ "name": "n8n-monorepo", "version": "1.69.0", "private": true, "engines": { "node": "20.x" },

I'm on Arc browser and using new canvas (might come from Arc actually I will try with Chrome)

@Louis-pa what happens when you try to delete a node? Do you see any errors or does it just not do anything? If you check your browser console does it show any errors?

Are you also connecting directly to your n8n instance or are you going through a reverse proxy, If you are going through a reverse proxy which one are you using?

I got this in console : TypeError: Cannot convert undefined or null to object at Function.keys () at deleteConnectionsByNodeId (:5678/assets/NodeVie…NfOOUof.js:33479:48) at deleteNode (:5678/assets/NodeVie…CNfOOUof.js:32886:5) at onDeleteNode (:5678/assets/NodeVie…CNfOOUof.js:34375:7) at callWithErrorHandling (:5678/assets/index-40I5DMGP.js:2169:19) at callWithAsyncErrorHandling (:5678/assets/index-40I5DMGP.js:2176:17) at emit (:5678/assets/index-40I5DMGP.js:7027:5) at onDeleteNode (:5678/assets/NodeVie…CNfOOUof.js:31877:7) at callWithErrorHandling (:5678/assets/index-40I5DMGP.js:2169:19) at callWithAsyncErrorHandling (:5678/assets/index-40I5DMGP.js:2176:17)

Nothing really happen when I try to delete a node, expect in console. 

I'm connecting directly to my n8n instance, it runs locally for now.

Hey @Louis-pa, I also tried importing quite a few workflows to my local instance using Arc browser on Mac and couldn't reproduce. I have a few more questions:

1. How are you importing a template? By clicking the Use Workflow button on the website or copying the template JSON?
2. Is the error happening when you try to delete a node via keyboard shortcut or clicking delete button for the node?
3. Can you confirm this only happens for you on the new canvas?

Thanks in advance
