What happened?

The issue is related to the latest build where there seems to be an issue with the trace line of the debugger (Toolbar) when the file attribute is not available.

output log of the trace line causing this issue

Array
(
    [function] => read
    [class] => CodeIgniter\Session\Handlers\DatabaseHandler
    [object] => CodeIgniter\Session\Handlers\DatabaseHandler Object
        (
            [DBGroup:protected] => default
            [table:protected] => ...

Steps to Reproduce

Update from 4.1.5 to 4.1.6.

Expected Output

Maybe check if the file attribute is set?

if (!isset($traceLine['file'])) { ...then do the clean-up? }

Anything else?

No response

Thank you for reporting.

Could you show us how to reproduce?
Updating from 4.1.5 to 4.1.6 does not reproduce this error, because we don't have your code.

[iprixi]

@kenjis As I have mentioned earlier, if you perform a read on any model, the trace line will have the type of function read and since there is no file attribute available on that trace line, an error of undefined index file will be thrown.

Updating itself is not going to throw errors, it's for when you get data from a table/model and CI_DEBUGGER is enabled. this change (I have referenced it earlier) was added in the latest release (FYI).

I'm getting the same bug. Not sure how to reproduce it but adding a check before accessing the file key fixes it as @iprixi suggested.

Here's an example of the $traceLine without the file key if it can help:

Same here, there is no file key.

Correct i also faced same error. it only occur when you set CI_DEBUGGER true. I was using v 4.1.5 and composer installation

[cijagani]

As temporary solution, i have modified toolbar.php file and removed database collector.

Same issue here. Caused by commit e97b95b

[kenjis]

Could anyone show us the minimum code that reproduce the error?
for fixing the error soon.

We need to write test code.

Note, we expect all code changes or bug-fixes to be accompanied by one or more tests added to our test suite to prove the code works. If pull requests are not accompanied by relevant tests, they will likely be closed. Since we are a team of volunteers, we don't have any more time to work on the framework than you do. Please make it as painless for your contributions to be included as possible. If you need help with getting tests running on your local machines, ask for help on the forums. We would be happy to help out.

I encountered a similar phenomenon.
It worked when I disabled the following in .env.

app_sessionDriver = 'CodeIgniter\Session\Handlers\DatabaseHandler'
app_sessionSavePath = 'ci_sessions'
app_sessionExpiration = 36000

So I wonder if the logic around the session using DB is the cause.
