tpz file errors importing at command line but works in the GUI

[hillcountryfare]

When I try to import this tpz file from the command line using calibredb, I get an error:

C:\dropbox\books>"C:\dropbox\for home\Calibre Portable\Calibre\calibredb" add --with-library "c:\dropbox\for home\Calibre Portable\Scratch Library" "C:\dropbox\books\Library\Sometimes I Act Crazy.tpz" -I source:901
Traceback (most recent call last):

ValueError: 'C:\dropbox\books\Library\Sometimes I Act Crazy.tpz': Invalid Topaz format - no metadata record
The following books were not added as they already exist in the database (see --duplicates option or --automerge option):
  Sometimes I Act Crazy
    C:\dropbox\books\Library\Sometimes I Act Crazy.tpz

Note, this book did not exist in the database.

When I add through the GUI, it imports fine as an htmlz file. debug log from the GUI and the tpz file attached.

Whatever install you are running calibredb from doesnt have the dedrm plugin installed. And use --duplicates if you want to add it anyway despite there already being a book with the same title in your library.

Can you offer some suggestions on troubleshooting or next steps? The calibredb page doesn't have any information on plugins.

The calibredb.exe file is in the same folder as the calibre-portable.exe that I launch and the import is successful with. I am also able to import a DRM'd azw3 file using the exact command except for changing the file name.

PLugins are loaded from the config directory. calibre-portable.exe works by setting an env var to point to the portable directory. If you are trying to use command line tools from a portable installation you need to set the env var yourself so that they use the correct config directory. https://manual.calibre-ebook.com/cus...ment-variables

thank you. setting CALIBRE_CONFIG_DIRECTORY solved the issue!
