[Python] "unsupported type for timedelta hours component: str" [closed]

I am getting the following error when running a TAXII connector in OpenCTI. This used to work without any problems with an older version.

{"timestamp": "2025-02-13T11:01:50.017793Z", "level": "ERROR", "name": "TAXII2", "message": "unsupported type for timedelta hours component: str", "exc_info": "Traceback (most recent call last):\n File "/opt/opencti-taxii2/connector/connector.py", line 113, in process_message\n added_after = datetime.now() - timedelta(\n ^^^^^^^^^^\nTypeError: unsupported type for timedelta hours component: str", "taskName": null}

The code at line 113 as follows.

# Performing the collection of intelligence
# Convert last_run to RFC-3339
dt_format = ""
if current_state is not None and "last_run" in current_state:
dt = datetime.fromtimestamp(last_run, tz=timezone.utc)
dt_format = dt.strftime("%Y-%m-%dT%H:%M:%S.%fZ")

if self.config.enable_url_query_limit and self.config.taxii2v21:
self.taxii2.filters["limit"] = self.config.url_query_limit
# Set added_after to either last run or initial history
if current_state is not None and "last_run" in current_state:
self.taxii2.filters["added_after"] = dt_format
else:
added_after = datetime.now() - timedelta(
hours=self.config.initial_history
)
self.taxii2.filters["added_after"] = added_after

stix_objects = self._collect_intelligence()


I am not a coder so not sure how to fix it. Any help appreciated. Thanks
