Urgunet help needed. Pyodide code is gone and not visible after updating to v2.3.5

[Ustym_Buchko]

Describe the problem/error/question

After I updated my environment to v2.3.5 from v1.123 (most likely, didn’t notice the exact version), all my Python code nodes that contained Pyodide code, are not showing previous code at all. I was aware about the breaking change but in my understanding I should be able to just modify the code after update to follow the change. However now I can’t see code in any of my nodes. After I select Python or JS, it just resets it to plain example.

What is the error message (if any)?

Please share your workflow

This is just an example of a node, I have around dozens of them across many workflows

Share the output returned by the last node

Problem in node ‘Combine preferences data‘
Could not get parameter

By that output I suppose that previous code that was using data retrieving from previous node with _input.all() still exists somewhere but is not visible for some reason.

Information on your n8n setup

That’s what I have in the object of code node:
{
“parameters”: {
“language”: “python”
},
“type”: “n8n-nodes-base.code”,
“typeVersion”: 2,
“position”: [
64,
-160
],
“id”: “8c04bc05-6234-41fd-a912-33a13e12b942”,
“name”: “Combine preferences data”,
“executeOnce”: false
}

Don’t see code here unfortunately

Same problem here. In my case, every execution before the update is gone.

[Ustym_Buchko]

yes, no code displayed there as well and the same error in Language field that python value is not supported

[Andrea_Riba]

same problem here

i’d say horrible experience with the latest updates, disappearing nodes and codes

Thanks a lot for bringing the problem to our attention. That was definitely not intended like that. Sorry for the problems it caused. A PR has already opened to fix the issue:

fix(core): Route both Python options to the native Python runner

[igorlaltuf]

Just updated to version 2.3.6, but the issue still persists.

New version [email protected] got released which includes the GitHub PR 24511.
