Understanding this Ipython related error in cluster logs

Hi Databricks Community !

I'm having this error from a cluster's logs :
[IPKernelApp] ERROR | Exception in control handler:
Traceback (most recent call last):
File "/databricks/python/lib/python3.10/site-packages/ipykernel/kernelbase.py", line 334, in process_control
await result
File "/databricks/python/lib/python3.10/site-packages/ipykernel/kernelbase.py", line 797, in inspect_request
reply_content = self.do_inspect(
File "/databricks/python/lib/python3.10/site-packages/ipykernel/ipkernel.py", line 517, in do_inspect
bundle = self.shell.object_inspect_mime(
File "/databricks/python/lib/python3.10/site-packages/IPython/core/interactiveshell.py", line 1867, in object_inspect_mime
return self.inspector._get_info(
File "/databricks/python_shell/dbruntime/safe_oinspect.py", line 712, in _get_info
return self.format_mime(_mime)
File "/databricks/python/lib/python3.10/site-packages/IPython/core/oinspect.py", line 617, in format_mime
assert isinstance(bundle["text/html"], list)

I have no idea what this is meaning, and I would like to better understand how to solve this.

The cluster is a Single Node, without Unity Catalog. Multiple users are running pandas notebooks at the same time on it. It has the following configuration :

"spark_version": "13.3.x-scala2.12",
"spark_conf": {
"spark.databricks.delta.preview.enabled": "true",
"spark.master": "local[*, 4]",
"spark.databricks.cluster.profile": "singleNode"

"data_security_mode": "NONE",

Does anyone know why is this error showing up ?

Many thanks for your help
