Bug Description

I recently updated my version of skript from 2.7.0b to 2.7.0, with the new version every time I run any command to reload the scripts I get this error. Under these conditions I cannot continue to work efficiently on my project, my server runs on paper, and the version is 1.19.4:

Expected Behavior

it should reload the script

Steps to Reproduce

there must be a problem with my script, that's what gives me this error, because I tried to reload a test script and it works. But recently I haven't added any particular functions to the one that gives errors.

However, to replicate it to me, just type /sk reload (file name)

Reopening since first issue submitter has gone vanished.
Can you send your code where you use variables: section?

[Moderocky]

Thanks for finding this, it looks like both here:

and here:

the data is assumed to be present, whereas in fact the method used has a nullable result

Either we need to work out why the value isn't present (when it seems like it ought to be) or as a safety alternative we could either use the default supplier or check if the value is null and do something about that.

In both cases we probably ought to have some kind of null check here.

[arnigel2000]

perhaps this is where the problem might be

on place:
    if "%region at event-block%" contains "hacking in world pixelnovia":
        if event-block is Redstone Comparator:   
            set {_amount} to placeholder "playerlist_donors_amount" parsed as integer 
            if {_amount} < 1:
                send "&cnon ci sono abbastanza poliziotti online" to player
                cancel event
            else:
                send "&aHacking iniziato...30 secondi all'apertura del cavò!" to player

or here

variables:
    {haraccolto.droga} = false

command /raccogli droga:
    trigger:
        if {_amount} < 1: 
            send "&4non ci sono abbastanza poliziotti online!" to player
        else:
            if player is in region ("serra1"):
                if {haraccolto.droga} = false:

                    send "&ahai iniziato a raccogliere..." to player

[arnigel2000]

How is the resolution of the problem going? At the moment I can't work with variables on script, which is a big problem for me, and moreover to restart the script I have to restart the whole server. I don't want to be rude but I think that if the problem is not resolved I will be forced to put the previous version of script, hoping that everything goes well there.

[Moderocky]

I have been unable to reproduce this error so far.
If somebody else can then we may be able to fix it in time for the next release in 11 days.

Can you provide the code that is causing this error?

[APickledWalrus]

@arnigel2000 Can you confirm whether you have two variables: structures in the offending script? Using two at once in the same script may cause this error.

[arnigel2000]

The 2 variables are in the same script, but it's strange because until now it worked, anyway I'll try to put them in two different scripts. However, the variable I use in the first and second cases "{_amount}" is a placeholder that I got from a plugin named "Playerlists". Maybe that caused problems.

[arnigel2000]

thanks to your advice skript started working again, probably the problem was the two variables within the same script, thanks for the support.
