Python SDK: async_capture_scaled_screen_region_to_buffer results in PRL_ERR_NO_DATA

I am trying to capture a screen of a running Parallels VM, in Python.
An SDK sample program which captures the screen to a file runs OK, but when I try to capture the screen in a buffer the job results in
PRL_ERR_NO_DATA error.

Working:

Code:

vm_io.sync_capture_screen_region_to_file(VM, current_screen, consts.PIF_BMP)

Not working:

Code:

    job = vm_io.async_capture_scaled_screen_region_to_buffer(VM, \
        format=consts.PIF_RAW, \
        x=0, y=0, width=100, height=50 )
    wait_job = job.wait()
    result = job.get_result()
    print result
    if not result: print job.get_error()

which results in:

Code:

None
Error: SDK error: 0x80000014: PRL_ERR_NO_DATA PRL_ERR_NO_DATA

Parallels Desktop Home Version 16.0.1 (48919)
SDK just downloaded today

 

Hello, could check the same behavior with the newest Parallels Desktop update - 16.1.1. please and provide us with any results

 

This is still an issue with Parallels Desktop for Mac Pro Edition 17.1.1. SDK just downloaded today. The result is always PRL_ERR_NO_DATA no matter what the parameters are.
