Locust put request is randomly failing

My locust file has put requests but sometimes it's passing sometimes failing. Can anyone explain why that's happening?
Here is my locust file
def _generate_put_data(self) -> str:
if len(self.ids) > 0:
teacher_name = self.generate_random_string()
teacher_email = f"{self.generate_random_string()}#{self.generate_random_string()}.{self.generate_random_string()}"
teacher_email = teacher_email.replace("#", "%40")
teacher_id = str(random.choice(self.ids))
request_string = f"{self.path_all}/{teacher_id}?teacherName={teacher_name}&teacherEmail={teacher_email}"
return request_string
#task(2)
def put_request(self):
self.client.put(url=self._generate_put_data())
...
_generate_put_data method returns a string, which is a query.
Here is the error:
[2023-01-26 11:39:12,357] pop-os/ERROR/locust.user.task: expected string or bytes-like object

How to read Interbase database with Cyrillic text content

I am using pyfirebirdsql version 0.8.5 to connect to Interbase database.
import firebirdsql
conn = firebirdsql.connect(
host='192.168.133.121',
database='E:\\test\test.gdb',
port=3050,
user='sysdba',
password='masterkey'
#charset="WIN1251"
#charset="UTF8"
)
cur = conn.cursor()
cur.execute("select column1 from table1")
for c in cur.fetchall():
print(c)
conn.close()
When I try to run the script I get the following:
Traceback (most recent call last):
File "123.py", line 15, in <module>
for c in cur.fetchall():
File "/usr/lib/python2.7/site-packages/firebirdsql/fbcore.py", line 291, in fetchall
return [tuple(r) for r in self._fetch_records]
File "/usr/lib/python2.7/site-packages/firebirdsql/fbcore.py", line 225, in _fetch_generator
stmt_handle, self._xsqlda)
File "/usr/lib/python2.7/site-packages/firebirdsql/wireprotocol.py", line 728, in _op_fetch_response
return self._parse_op_response() # error occured
File "/usr/lib/python2.7/site-packages/firebirdsql/wireprotocol.py", line 210, in _parse_op_response
raise OperationalError(message, gds_codes, sql_code)
firebirdsql.OperationalError: arithmetic exception, numeric overflow, or string truncation
Cannot transliterate character between character sets
Adding charset both "WIN1251" and "UTF8" doesn't solve the issue. Do you have any ideas?

neomodel giving Attribute error on save

I am running the following config for neo4j:
neo4j - 3.0.0
py2neo - 2.0.8
neomodel - 2.0.2
Finally, the code I try to run is:
class User(neomodel.StructuredNode):
user_id = neomodel.IntegerProperty(unique_index=True, required=True)
name = neomodel.StringProperty()
phone_number = neomodel.StringProperty()
user = User(user_id=6, name='Sourabh Dev', phone_number='9711237840').save()
I don't understand, why I keep getting this strange error. Am I doing something wrong here or should I use py2neo instead of neomodel?
My traceback is:
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'TypeError'

Two points here:
Existing Neomodel doesn't support the Neo4j 3.0
Cypher syntax has changed in 3.0, so the error raises.
In 2.x , MATCH n RETURN n
In 3.0 , MATCH (n) RETURN n
Node n is enclosed in braces.

pymssql bulk insert error (python)

Trying to bulk insert a CSV file using pymssql here's the code:
conn = pymssql.connect(host='server', user='user', password='secret', database='My_Dev')
cur = conn.cursor()
load = 'BULK INSERT TempStaging FROM \'/home/dross/python/scripts/var/csv/' + f + '.csv\' WITH (FIRSTROW = 1,FIELDTERMINATOR = ',',ROWTERMINATOR = \'\\n\') GO")'
cur.execute(load)
When executing get following error:
Traceback (most recent call last):
File "./uploadResults.py", line 46, in <module>
cur.execute(sweepload)
File "pymssql.pyx", line 447, in pymssql.Cursor.execute (pymssql.c:7092)
File "_mssql.pyx", line 1009, in _mssql.MSSQLConnection.execute_query (_mssql.c:11585)

File "_mssql.pyx", line 203, in _mssql.ensure_bytes (_mssql.c:2733)
AttributeError: 'tuple' object has no attribute 'encode'
Line 46 is cur.execute line

Note that .format() could allow sql injection, but if you control the filename then it's not that bad (not sure if a parameter would work here).
Also, you should use triple-quoted strings when dealing with SQL, your life will be so much better. Like this:
load = '''BULK INSERT TempStaging FROM /home/dross/python/scripts/var/csv/{}.csv WITH (FIRSTROW=1, FIELDTERMINATOR=',', ROWTERMINATOR='\n')'''.format(filename)
Being triple quoted, you can also break it up to make it easier to read:
load = '''
BULK INSERT TempStaging
FROM /home/dross/python/scripts/var/csv/{}.csv
WITH (
FIRSTROW=1
, FIELDTERMINATOR=','
, ROWTERMINATOR='\n'
)
'''.format(filename)

You should defined the string as below:
load = "BULK INSERT TempStaging FROM /home/dross/python/scripts/var/csv/" + f + ".csv WITH ( FIRSTROW=1 , FIELDTERMINATOR=',' , ROWTERMINATOR='\\n')"
