I have written the below python function (a snippet of the full code) to work in AWS Lambda. The purpose of it is to take a GeoJSON from an S3 bucket and parse it accordingly.
Once parsed, it is placed back into JSON format (data
) and then should be inserted into the specified database using
bulk_item['uuid'] = str(uuid.uuid4())
bulk_item['name'] = feature_name
bulk_item['type'] = feature_type
bulk_item['info'] = obj
bulk_item['created'] = epoch_time
bulk_item['scope'] = 2
data = json.dumps(bulk_item)
print(data)
self.database.upsert_record(self.organisation, json_doc=data)
except Exception as e:
print(f'Exception: {e.__class__.__name__}({e})')
The db_access file in which the above is relating to is another python script. The function upsert_record
is as below:
def upsert_record(self, organisation,
json_doc={}):
My code is working perfectly until I try to upsert it into the database. Once this line is gotten to, it throws the error
Traceback (most recent call last):
File "/var/task/s3_asset_handler.py", line 187, in process_incoming_file
self.database.upsert_record(self.organisation, json_doc=data)
File "/opt/python/database_access.py", line 1218, in upsert_record
new_uuid = json_doc['uuid']
TypeError: string indices must be integers
I can't seem to figure out the issue at all
CodePudding user response:
You are trying to get an element from a JSON object, but passing a string.
The
data = json.dumps(bulk_item)
creates a string representing the object.
Try using bulk_item
on it's own.
