[Error] Trying to turn HMs into items with outdated plugins (v21.1)

[UltraPokeMaster01]

Hello again

After the release of version 21.1, I am trying to migrate everything I've currently added to my project over to the new version, since I feel that it'll be a major help. However, I've had troubles when coming to turning HMs into Items

After adjusting the "pbHasItem?" lines into "$bag.has?" lines, I tried testing the HM code with surf. However, when selecting yes to wanting to surf, it crashes with this error message:

It has happened with other HM-related plugins too, all with surf. How would I fix this please?

Hi, @UltraPokeMaster01
It seems that the error message that you meant to send hasn't shown up. Could you maybe try again, please?

Whoops, I tried to turn the image into a link because it seems that's the only way this website will accept the images, ig it didn't turn out that well. If i just send the link, hopefully copy/pasting it will send you to the right place. If not, is there another, easier way for me to do this?
