Google表格-从许多文件中查询和导入范围

Question

I´m using Google Drive Sheets for colection data from many users - there is about fifty files with same structure. That files are "alive" but I need analyse them by filters all together etc.

=QUERY(
{
IMPORTRANGE("xxxx";"JedenKlient!A3:N");
IMPORTRANGE("yyyy";"JedenKlient!A3:N");
...
IMPORTRANGE("zzz";"JedenKlient!A3:N")
};"where Col1 is not null")

When I use this QUERY and IMPORTRANGE with 2 files - its working well. After I put there more files - Google Sheets send me back error "in ARRAY_LITERAL - missing values". I found somethings "about different numbers of columns" but my files have the same structure - of course - different numbers of rows...

Can you please help me fix this issue?

Thank you,

Solved - I must put every IMPORTRANGE to cell and click on popup button. This need to be done file by file. Unfortunately.

After that whole query start working.
