PL0024 : Preloading data were not found

Hi am failing to upload assignments , getting this error:“PL0024 : Preloading data were not found”. What could the problem be?

Hello @andrewmupere ,

the error is rather generic and appears when Survey Solutions doesn’t understand how to use the file that you are uploading in relation to the questionnaire which you are trying to preload.

In the simplest case, it can be provoked by uploading an empty zip-archive of assignments to any questionnaire, as in the illustration below:

To be certain, examine the preloading file in conjunction with the questionnaire where you create assignments.

Best, Sergiy
