It happens when an lime 4 SID is imported also.
For us... Lime6 on PHP 8.0 and higher is just not working due to this error...
I'm on LimeSurvey Community Edition Versie 6.3.9+231211 now!
I analysed that application/models/Survey.php
public function getTokenAttributes()
is the problem showing the KEY() error. It always is 500 during this function!
And reading the comments in source tells me '// don't know why yet but this breaks normal tokenAttributes functionning' Strange behaviour detected!?

When debug=1 of 2 the same debug pops up on PHP 7.4!
But PHP 7.4 and debug =0: Lime6 does not crash!
On PHP 8 it does crash when debug=0!!! So the problem is there a long time.. hence the comments in the code!?
I wil try to dig in this further!

Got it!!!!

application/helpers/common_helper.php
line 2946

$aSavedExtraTokenFields = Survey::model()->findByPk($surveyid)->tokenAttributes;
change to:
$aSavedExtraTokenFields = Survey::model()->findByPk($surveyid)->tokenAttributes ?? [];

In PHP 7 it is a warning
in PHP 8 it's a 500! $aSavedExtraTokenFields is not allowed to be NULL anymore! in function array_intersect_key()!

change to
$attdescriptiondata = decodeTokenAttributes($this->attributedescriptions ?? []);
In PHP 7 it is a warning

Further assessment of the problem.
The 500 occurs when a SID without Tokens is run, imported or edited!
And that is consistent with both Token function issues... No Tokens then array of tokens should be an empty array ([])
I think this is the root of the problem!

We have another system running on PHP 8.2 without problemns but all the SID's are Tokenized!!

I'm always struggeling with GitHub

but
in application/helpers/common_helper.php on line 2946:
$aSavedExtraTokenFields = Survey::model()->findByPk($surveyid)->tokenAttributes ?? [];

and in application/models/Survey.php on line 667:
$attdescriptiondata = decodeTokenAttributes($this->attributedescriptions ?? []);

Has resolved the issue!

made another commit.. so Github will pass the code!

reverted survey.php to
$attdescriptiondata = decodeTokenAttributes($this->attributedescriptions ?? '');

but then the bug is there again!

so somehow $attdescriptiondata is of the wrong type here! Github checks is not detecting this!
That's way it is hard to debug (also with lime debug=2)!

So again (very strange): on line 670 of survey.php:

key(reset($attdescriptiondata))
is clearly an error here!
$attdescriptiondata is an array!
reset($attdescriptiondata) will reset the pointer in the array en returns the first element!
In my case the element is a string/numeric not an array!
so key() will die in >8.0 because the result of reset($attdescriptiondata) is not an array!!

I guess when SID is tokenized the first element of the array is also an array!!!

So I made this correction in GitHub...
Hopefully this wil pass and the fix is legit!

so inserted after line 667 in models/Survey.php (after a couple of space missing issues) :
if (!is_array(reset($attdescriptiondata))) {
$attdescriptiondata = null;
}
And for the sake of it.. in my case with this fix the issue is fixed!

I replied to Kevin:

Why do you call reset() here?

Contributor
Author
@BertHankes BertHankes 1 minute ago
Because the reset() function is used by the native code on line 670:
if ($attdescriptiondata && strpos((string) key(reset($attdescriptiondata)), 'attribute_') === false)

And if reset() is not returning an array (in this case a NULL).. key() gives a 500
In trying to debug it is/was very hard to get to this state... strpos(key(reset($attdescriptiondata))... has 3 functions in one line.

The reset(array) is returning null because there are no tokens!

From PHP help:
reset() rewinds array's internal pointer to the first element and returns the value of the first array element.
The value returned by reset(), when not having tokens, is null!

And in PHP<8 it was all good.. but now it is strict! Key(NULL) is not allowed anymore and results in 500
