Problem uploading collected archive

Good day,

I got the following error when attempting to upload my assignments
“PL0040: File with questionnaire level data is missing.”

I double checked my zip file and I seem to have all the files required, Could you tell me what data I may be missing from my file to upload my assignments ?

Users experiencing problems with preloading data to Survey Solutions should consult the “preloading troubleshooting section”:http://support.mysurvey.solutions/customer/en/portal/articles/2928007-errors-in-user-supplied-files-for-preloading . The errors reported by Survey Solutions are self-explanatory for the most part. For the cases where interpretation of the error message is not obvious the comments in that article should help track down the issue.

yes I have already made precharging with previous surveys
