Error "array_key_exists(): The first argument should be either a string or an integer"

Question

I'm using Laravel for my project, and I need to generate no_track from the id of the record, created_at->hour and created_at->minute. I can save the data to the database, but I can't save the data to the database after creating the no_track. The error messages said:

array_key_exists(): The first argument should be either a string or an integer.

I attached an image of the error message. When I save the data to the database I want to get no_track from the id of the record, hour and minute and save the no_track to the no_track field.

I got this error messages

This my form code:

Answer 1

In my case there is no error in the code, then i restart my local server but nothing happen I cleared my cache,views,rerun server, composer dump-autoload but nothing should work. Solution

I terminate the current project server and run another project,
this project is run successfully, and after this I run my current project so it works like a charm.

Answer 2

In my case error is in this line:

    $attrs = Attribute::get();
    $attribute_ids = $attrs->map->only(['id']); // solved

    $attrs = Attribute::get();
    $attribute_ids = $attrs->get(['id']); // here was my error

i replace first

and the second not worked

this is the error occurred
