Describe the bug
A clear and concise description of what the bug is.
When I click on a vendor with items to sell in my bag I get 4 Lua Errors:
Message: Interface\AddOns\Scrap\addons\main\main.lua:189:attempt to compare nil with number
Time: Tue Oct 13 23:05:23 2020
Count 4
Stack: I'm sorry I can't re-type the entire error messages.

To Reproduce
Steps to reproduce the behaviour:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'
4. See error

Expected behaviour
A clear and concise description of what you expected to happen.
Well, what was happening before Shadowlands was I'd click on a vendor and Scrap would auto sell all my unusable items all at once. I guess that's the expected behaviour for this error?

Screenshots

I have a screenshot, but I'm unsure how to get it to you. I don't see anything about attacking a file.

People have added pull requests but he doesn't seem to be too active on this addon anymore.

Here's a fork that I just updated to have at least basic functionallity https://github.com/rainfordays/Scrap

Hm, doesnt work for me even with Rainfordays' version

Unfortunately no (I assume that would make troubleshooting a lot easier), I don't see the buttons on the merchant frame, but I can access the settings from Interface. I think I have the right files? What I did was replacing the scrap main folder from Twitch with your version, so I currently have these 3 scrap folders in my addons folder https://imgur.com/a/XqcLgQp

I just noticed that in my Addon Control Panel window it says that Scrap Merchant and Scrap Options are missing a dependency, and I also don't see Scrap in my addon list, hm weird. I looked into the scrap-master folder and these are the files I have

Remove the old Scrap folder and then Rename the folder you downloaded from Scrap-master to just Scrap

The addon

Do you get any errors?

Unfortunately that didnt do anything, still nothing :/

However I did try to add something to my junklist (just from the keybind, still cant see any of the UI elements at the vendor) and then I got this lua error

2x [string "SCRAP_TOGGLE"]:3: attempt to index global 'Scrap' (a nil value)
[string "SCRAP_TOGGLE"]:3: in function <[string "SCRAP_TOGGLE"]:1>

Locals:
keystate = "down"
item = "|cffffffff|Hitem:152579::::::::50:262:::::::|h[Storm Silver Ore]|h|r"
(*temporary) = nil
(*temporary) = nil
(*temporary) = "|cffffffff|Hitem:152579::::::::50:262:::::::|h[Storm Silver Ore]|h|r"
(*temporary) = "Storm Silver Ore"
(*temporary) = "|cffffffff|Hitem:152579::::::::50:262:::::::|h[Storm Silver Ore]|h|r"
(*temporary) = nil
(*temporary) = "attempt to index global 'Scrap' (a nil value)"

What it's saying is that the addon Scrap isn't loaded.

You downloaded the thing from my branch, the folder that you get is called 'Scrap-master', it has to be named just 'Scrap'.

In your addons folder there should be

• Scrap
• Scrap_Config
• Scrap_Merchant

Yep i got those

Me and Gaveer fixed it in discord, the issue was on my end, the addon is working for me now
