Run batch command line in Fu console beginning with 'gimp'

[Gimpnik]

If I run the following code in Fu console

Code:

(gimp -i -b '(batch-crop-to-content "D:\Test\*.png")')

or

Code:

(gimp -b '(batch-crop-to-content "D:\Test\*.png")')

so I receive the following error message:

Code:

Error: syntax error: illegal token 1

 
Please help to understand this error.
 
I would like to run the command line via a batch script, but I receive only
"batch command executed successfully" and cant' see more details.
 
How to force detailed output for gimp-2.10.exe console without "echo off" to be able to see for possible errors in the chain of procedures?
In the batch script I have explicitly set "echo on" but this not help here, because gimp-2.10.exe is started as a separate process.
 
Thanks
