AusPost shipping methods stopped working

[ax2000]

Hi there, A client just reported that the AusPost shipping methods stopped appearing on the checkout flow of their website. I've tried to do some debugging but I can't figure out what the issue might be.

It was working correctly up until now and nothing within the Postie settings had been updated, so not sure if something might have changed on AusPost's side?

Things I've tried/tested:

• Checked that commerce config unit is set to g and mm
• Checked config settings both through postie.php and via CP
• Made sure products were setup with the right units and with dimensions and weight added

The API connection status in the Postie CP appears as Not Connected and when hitting refresh I get the error below (which from memory it used to connect correctly when I set it up originally)

Additional info

• Plugin version: 2.4.8 (When detected the issue it was 2.4.7 and I updated to latest version in case it was due to that)
• Craft version: 3.7.4 (When detected the issue it was 3.6.16 and I updated to latest version in case it was due to that)
• Multi-site: No

Additional context My postie.php looks like:

return [
    '*' => [
        'pluginName' => 'Shipping Providers',
        'hasCpSection' => true,
        'enableCaching' => true,
        'displayDebug' => false,
        'displayErrors' => false,
        'manualFetchRates' => false,
        'fetchRatesPostValue' => 'postie-fetch-rates',
        'providers' => [
          'australiaPost' => [
            'name' => 'AusPost',
            'enabled' => true,

            // API Settings
            'settings'   => [
                'apiKey' => 'xxxxxxxxxxxxxxxxxxx',
            ],

            // Mark-Up
            'markUpRate' => '',
            'markUpBase' => 'percentage',

            // Units
            'weightUnit' => 'g',
            'dimensionUnit' => 'mm',

            // Packing method
            'packingMethod' => 'singleBox',

            // List of provided services
            'services' => [
                'AUS_PARCEL_EXPRESS' => 'Express Post',
                'AUS_PARCEL_REGULAR' => 'Parcel Post',
            ],
          ],
        ],
    ]
];

Please let me know if you need any more info to try and replicate or if you need me to test anything else.

Thanks heaps, Alby

Looks like that testing functionality just needs to be tweaked, which I have done in the latest craft-3 branch, if you want to try that.

Otherwise, can you provide the storage/logs/postie.log log file?

Actually, I believe your units need to be kg and cm for use with Australia Post. The weight/dimension units used by your store's products is completely separate, and Postie will convert them for you. The units here are strictly for what units the box-packing algorithm should use, and therefore send to the provider's API. AusPost I believe only supports kg/cm.

Some providers allow changing the units used for the boxes being packed - and in fact some like FedEx and UPS will fail if your account is setup in one region and you try to use an unsupported unit.

If you can test changing those units?

Thanks for the prompt reply @engram-design .

I have updated the units to kg and cm and the shipping options appear correctly now, thanks heaps for that.
