[Question] Copy fails from local files to azure file storage - 404 errors

[Kapanther]

10.0.2 Preview - Win 7

Copy fails when I try a local file copy to-> azure file storage with the 10.0.2 preview. Works with current 8.1.0

this is the 8.1.0 line
azcopy /source:C:\GCDS_dev /dest:/https://azgcdsdevst1.file.core.windows.net/gcdsbuild/GQtest /DestKey:<retracted> /s /BlockSizeInMB:32

converted to 10.0.2 preview
azcopy copy C:\GCDS_dev https://azgcdsdevst1.file.core.windows.net/gcdsbuild/GQtest?<retracted_sas> --recursive=true --block-size=32

Results is all files fail with 404 errors in the log... any ideas?

Resolved. The problem was actually the key. i didn't realise you need the full "Query String" to perform copy operations. Similar to below.
