I'm trying to create a migration to add a foreign key to an existing column, it looks like this:
use Migrations\AbstractMigration;
class AddForeignKeyIndexToPoints extends AbstractMigration
{
public function up()
{
$this->table('points')
->addForeignKey('point_type_id', 'point_types', ['id'])
->save();
}
public function down() {
}
}
which fails like this:

There's at least one example in the Phinx docs that leads me to believe this should work, but I can't get it to - what am I doing wrong?
I have a task using the Laravel task scheduler than fires perfectly.
It fires to call a public method named Task::checkSpiders().
This hits an API (works fine) then should update local DB accordingly.
If i create a route as so...
Route::get('/test', function () {
$test = Task::checkSpiders();
}
It run's perfectly.
When i run it from CRON however it throws me this error...

The code to insert to the DB ( I don't think is relevant but i'll add in anyway..)
$tasks = DB::table('tasks')
->where('id', $id)
->whereNull('end')
->update([
'status' => $status,
'start' => $start,
'end' => $end,
]);
Also, just a note I am running this in Docker using Supervisord to manage CRON with Laravel.
Any help much appreciated!
Stupid Mistake;
CRON is running under a different user thus the enviroment variables loading from .env aren't available.
I checked this by logging the ENV variables from a task run in CRON.
Like so...
Log::info(json_encode(get_defined_vars()));
That returned [] an empty array.
I've since hardcoded the variables to the config and all is working perfectly.
Alternatively I could have set the ENV Variables in PHP (Incase they are used elsewhere) using...
<?php
putenv("KEY=value");
?>
Here is what I get and I don't know what to do....

write your zend query in a try block
and
catch the exception
Zend_Db_Statement_Mysqli_Exception (check which one you are using 'mysql' or 'mysqli' or 'PDO') in the exception catch code just call {model}->getDefaultAdapter()->closeConnection() and then again call the zend query you have got.
this should solve your problem.
NOTE: Below code is just for reference and should not be used as it is (may have error in it).
try
{
$user = {model}->fetchRow(array('user_id = ?' => $senderid));
}
catch(Zend_Db_Statement_Mysqli_Exception $zenddbmysqliexc)
{

$user = {model}->fetchRow(array('user_id = ?' => $senderid));
