Grey screen when trying to scan it in VAT app!

[ZED-Magdy]

Hi,
this is my code I just copied it from your blog

when trying to scan the qr in VAT app it gives a Grey screen,
I've created a nodejs service to generate the base64 TLV,
it works fine untill the seller name is arabic I'm using utf8 in encoding but still the same result,
is their any solution in both approaches?
PHP/Nodej?

nvm my bad sorry the package works fine I forgot to format the date to ISO8601

@ZED-Magdy i tried formatting invoice date to ISO8601 using carbon as of this
new InvoiceDate($invoice->created_at->toIso8601ZuluString()),
but the invoice reader keeps reading current date and time of the scanning process not the actual invoice date
did u faced this problem ?
