I'm trying to import some data from an Excel file.
My extension is version 26.1.0, the server I'm connected to is 19.28.0.0.0.
At first I did not understand I had to select the File before selecting the format (though that is indeed documented).
When I try to import this data 04_2026_Adressenlijst AZ en PZ_Liste d'adresses HG et HP.xls I get an error
DBTU-02500: An unexpected condition occurred that prevented the request from being fulfilled An unexpected error with the following message occurred: Cannot read the array length because "local16" is null. Retry the request, if the issue persists, report it to product support
I thought this had to do with the the headers spanning multiple columns (e.g. columns Q, BA etc), but the error message is somewhat cryptic.
I tried modifying the file, but now I get a different error
DBTU-02500: An unexpected condition occurred that prevented the request from being fulfilled An unexpected error with the following message occurred: java.lang.NullPointerException. Retry the request, if the issue persists, report it to product support
