I have been using client managed Qlik Sense for a while.  I have load scripts that work just fine.  They aren't working in Qlik Cloud.  The problem is the wild card in the file name:

LOAD
fields...

FROM [lib://...path.../../TD/2023 TD Quest - AM Asset Mgmt*.xlsx]
(ooxml, embedded labels, header is 1 lines, table is [AM Asset Management]);

Without the wild card it loads fine, but not with it.  All the files in the directory have a slightly different ending.  Not sure to work around this.
