I recently ran a study through Inquisit Web that repeatedly threw up an error across many participants (110/127 participants). The error report was as follows:
"Error 0. experiment_script - online.iqx Unknown system error. Line 344, File iqkey.cpp".
The error log for the study assigns this error a code "46".
0. experiment_script - online.iqx is a batch script used to run a series of tasks in sequence.
The data saved from most participants seems ok and not linked to the error code in any clear way.
I also could not find any mention of this error or similar .cpp errors in the forums or documentation. So my questions are:
1) What does this error reflect?
2) What are the possible causes and outcomes of this error? Is the error something to be concerned about?
3) Is there a place in the forums, documentation, or elsewhere that provides an index of Inquisit Web error codes and their meaning?
Thank you very much! :)

This error typically indicates an issue with /inputdeviice and /validresponse settings in your script, e.g. a trial or instruction navigation set to a keyboard key when the inputdevice is actually set to mouse (and hence a keyboard key is not valid input) or vice versa.
For anything more specific, you will have to provide the script.

Found the script(s). The issue is the /prevkey definition in two of your scripts <instruct> elements:
<instruct>
/ nextkey = (" ")
/ prevkey = (0)
/ prevlabel = " "
/ fontstyle = ("Calibri", 2.11%, false, false, false, false, 5, 1)
</instruct>
is invalid, 0 is the code for "no response" and cannot serve as back navigation key for instruction pages. Fortunately, this mistake is not critical in this case and will not have adversely affected the scripts' behavior. To get rid of the error, remove the /prevkey attribute from the <instruct> element.

Hello Dave,
Thank you very much for this informative response.
It is nice to know now where this error came from, and also that it is not a concern for this study at least!
Thanks again, and all best!
