Indexing error in Tobii Pro SDK

[esdalmaijer]

Dear Tobii devs (@grebdems @pedrotari7 ;) ),

An error was reported on the OpenSesame forum. I've copied the relevant error message below:

    return (status[1], [TobiiProCalibrationPoint(x) for x in result[1]])
IndexError: tuple index out of range

To me, it seems like an issue in the tobii_pro module, where either status has a length of less than two, or TobiiProCalibrationPoint has a length of less than result[1]. Any thoughts?

Thanks for your consideration! Edwin

Yes we are aware of it! Currently working on a fix for this bug.

[esdalmaijer]

That's amazing! Thanks! :)

Thanks Edwin for signaling this bug. We got a Tobii X2-60 and we are actually stuck because of this, I hope it will be fixed soon.

@esdalmaijer @vmoscati I've published a new version of the Tobii Pro SDK (1.3.1). It's available both in Tobii Pro's website and in pypi! Thank you for bringing this bug to our attention 👍

[esdalmaijer]

Wow, that is incredibly quick! Thanks, guys! :)

@pedrotari7 @esdalmaijer Now calibration works, many thanks!
