Billmate checkout hash is missing about billmate-checkout-for-woocommerce HOT 4 CLOSED

I've been doing some debugging on this issue when the error happens. I'll post my findings and tests here.

Var dumping BCO_WC()->api->request_get_checkout( WC()->session->get( 'bco_wc_hash' ) ); shows the following error code:
Billmate Error Code: 50015. Checkout: Hash var tom

The session data is missing following keys:
bco_wc_number
bco_wc_checkout_url
bco_wc_hash

The session data still has the following set:
bco_wc_temp_order_id

Proposal
If bco_wc_hash is missing in user session data, init a new checkout and set a new hash. Would it be possible @NiklasHogefjord ? I'm trying to fix this temporarily myself as a lot of customers are reporting this issue (losing sales).

Edit:
I added the following in at the start of bco_init_checkout() in bco-functions.php to try and recreate the issue:

WC()->session->__unset( 'bco_wc_temp_order_id' );
WC()->session->__unset( 'bco_wc_hash' );
WC()->session->__unset( 'bco_wc_checkout_url' );
WC()->session->__unset( 'bco_wc_number' );

it seems that you're already doing what I proposed as these variables were set again even after unsetting them.

Edit 2:
In function bco_init_checkout(), if bco_wc_hash is missing, the following variable gets set to false:
$billmate_order = BCO_WC()->api->request_init_checkout();

Is this by design, or an error?

Edit 3:
I've cleared cache, opcache, redis and restarted Apache2. The error still occurs after those so I can rule those factors out.

Edit 4:
The "hash missing" error is gone if I go into the cart page and change quantities. So something requires a cart refresh when this error occurs. Not sure what's going on really. I'm thinking of adding a wc_fragment_refresh before loading BCO. Will try this later if I get the error again.

We need to discuss this some more @NiklasHogefjord.

Is this still an issue for you @DanielMarklund? We have released a couple of new versions and I can not reproduce this issue anymore.

Closing this for now. Please feel free to re-open it if it happens again.
