Method Field::getContext does not exist or is not callable

[BFD Calendar]

Just recently I'm getting errors when viewing or editing product pages, still using Padloper 1.3.0 on PW 3.0.123 with no recent upgrades or changes.

When just trying to access a page the error is 

Error: Exception: Method Field::getContext does not exist or is not callable in this context (in /home/mekanoinsa/www/wire/core/Wire.php line 519)

When trying to edit the error is

Error: Exception: Method Field::getContext does not exist or is not callable in this context (in /home/mekanoinsa/www/wire/core/Wire.php line 519) #0 /home/mekanoinsa/www/wire/core/Wire.php(386): ProcessWire\Wire->___callUnknown('getContext', Array) #1 /home/mekanoinsa/www/wire/core/WireHooks.php(723): ProcessWire\Wire->_callMethod('___callUnknown', Array) #2 /home/mekanoinsa/www/wire/core/Wire.php(442): ProcessWire\WireHooks->runHooks(Object(ProcessWire\Field), 'callUnknown', Array) #3 /home/mekanoinsa/www/wire/core/Wire.php(445): ProcessWire\Wire->__call('callUnknown', Array) #4 /home/mekanoinsa/www/site/modules/FieldtypeQRCode/FieldtypeQRCode.module(326): ProcessWire\Wire->__call('getContext', Array) #5 /home/mekanoinsa/www/wire/core/Wire.php(389): ProcessWire\FieldtypeQRCode->___wakeupValue(Object(ProcessWire\Page), Object(ProcessWire\Field), '') #6 /home/mekanoinsa/www/wire/core/Wire.php(416): ProcessWire\Wire->_callMethod('___wakeupValue', Array) #7 /home/mekanoinsa/www/wire/core/Page.php(1422): ProcessWire\W

Any idea what's going on?

Seems to be getContext() is available until 3.0.162?

By trial and error I managed to solve the issue. I had a 'qrcode' field on the product template and for some reason that didn't work. By removing the field in the PW template and the php file and even removing the module the error was gone.

No idea what one had to do with the other but anyway, problem solved.
