Traceback (most recent call last):
  File "/home/odoo/src/odoo/odoo/api.py", line 899, in get
    return field_cache[record._ids[0]]
KeyError: 1

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/odoo/src/odoo/odoo/fields.py", line 1083, in __get__

    raise CacheMiss(record, field)

The above exception was the direct cause of the following exception:

Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/home/odoo/src/odoo/odoo/http.py", line 658, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause
AttributeError: 'bool' object has no attribute 'astimezone'

CodeWasher

The root cause of the issue is that the code in the _compute_last_session method doesn’t handle cases where session[0]['stop_at'] might be False or missing. Adding a check to ensure session[0]['stop_at'] is a valid datetime object before calling astimezone() should resolve the problem. Additionally, reviewing the POS session data to ensure integrity will help prevent this issue in the future.

Hello Mozamel,

I hope you are doing well.

I wanted to explain the following code snippet:

1 Conditional Check:

- The line session and session[0]['stop_at'] checks if the session list is not empty and verifies that the stop_at key exists in the first dictionary of the list.

2 Time Zone Conversion:

- The expression session[0]['stop_at'].astimezone(timezone) converts the stop_at datetime to the specified timezone.

3 Data Extraction:

- The .date() method extracts only the date part from the datetime object.

The final result is assigned to pos_config.last_session_closing_date. If the session is not valid, it assigns False.

Here's the code for your reference:

I hope this helps!

Code :

self.pos_config.last_session_closing_date = (
session[0]['stop_at'].astimezone(timezone).date()
if session and session[0]['stop_at']
else False
)

Hi Mozamel,

You cannot access the session[0]['stop_at'] value directly. Print the result to check the output:

python Copy code print ( '\n session :' , session[ 0 ][ 'stop_at' ])

If the result is False , you need to ensure the condition is set correctly. Verify that session[0]['stop_at'] has the expected value before assigning it:

python Copy code if session[ 0 ][ 'stop_at' ]:
    pos_config.last_session_closing_date = session[ 0 ][ 'stop_at' ].astimezone(timezone).date()

Thanks & Regards,
