It seems that your problem could be reproduce with this one line:

  (format "%-*s" 10 "label")

It raises this error:

  (error "Invalid format operation %*")

and, indeed, I don't see the format control "%*" anywhere in the
'format' documentation, so, it looks like it's not a valid format
operation.

If you just copy/pasted a C 'printf' format, you probably should use
something like this instead:

   (format (format "%%-%ss" 10) "label")

HTH,
