Unable to approve quote on version 5.6.19

Hi,

On Client Portal, the approve button inside “Quotes” menu does not work. Upon clicking it, it only refreshes the page and does not change the status to “Approve”, I also would like to share the log error I’ve encountered after the button was clicked

[2024-01-24 03:45:47] production.ERROR: Trying to access array offset on value of type null {"userId":1945,"exception":"[object] (ErrorException(code: 0): Trying to access array offset on value of type null at /app/Http/Controllers/ClientPortal/InvoiceController.php:91)
[stacktrace]

I would greatly appreciate your response on the issue because our client is looking forward to resolve the approval of quote using client portal.

Hi,

@david do you have any suggestions?

Hi,
Hope all is well, I would just like to politely hear updates from this one.
