ERROR: Pyodide already fatally failed and can no longer be used. about n8n HOT 13 CLOSED

Thanks @Joffcom
As per your recommendation i will deploy the n8n in a container and will update.

Hey @rajubish,

Can you share the Python you are trying to run?

from n8n.

Hi @Joffcom

Below python code executing through n8n workflow.

import json

tenant_data = []
for item in _input.all():
    tenant_ids = item.json["tenant_ids"]
    print(type(tenant_ids))
    if tenant_ids:
        for tenantid, val in tenant_ids.items():
            tenant_data.append({"tenant_id": tenantid})
    print(tenant_data)
    print(type(tenant_data))
return tenant_data

from n8n.

To avoid duplication of work. This question got also posted to the forum:
https://community.n8n.io/t/workflow-getting-error-on-execution/42705

Please do in the future not post twice! That just causes unnecessary work for us. Thanks.

from n8n.

Understood. Can you get resolution for this error please.

from n8n.

Any update?

Hey @rajubish,

Typically we only work Monday to Friday during Berlin office hours but occassionally we will post on our own time outside of those hours in this case I have only just got to a stage where I am ready to look into this.

Just running the Python has not reproduced the same issue, Can you share the json input data as well.

from n8n.

Hi @Joffcom

Thanks for your response.
Here here the json input data.

Hey @rajubish,

This appears to be working as expected for me.

Running your workflow up to the second redis node is also ok, can you provide a contained workflow that reproduces this issue? Are you also using the docker image, running from npm or doing something else?

from n8n.

Hi @Joffcom

If i run manually then it works find without any issue, but if it's trigger from scheduler then it's failing.

Thanks

from n8n.

@Joffcom
I am running the n8n using npm in ubuntu machine.

Hey @rajubish,

Running it as a shedule doesn't appear to be causing an issue for me either, Can you try running n8n in a container as recommended and see if that has the same issue?

from n8n.

Moving to closed for now as we are not able to reproduce so I suspect it is a local issue.
