Trying to process WAV file with VST2 plugin. Get 'dropout' -> 0 frames output

[vtange]

Hello.

I'm trying to process music in WAV format through a De-esser plugin I save the settings for in an .FXP file.

Everything seems to checkout and the process finishes, but I get nothing written in the output file. All I get is

D 00294400 006302 Read 512 samples from PCM file
D 00294400 006302 Processing audio with plugin 'Lisp.dll'
D 00294400 006302 Plugin 'Lisp.dll' spent 0ms processing (0% effective CPU usage)

and finally

D 00294912 006302 End of PCM file reached
D 00294912 006302 Read 0 samples from PCM file
D 00294912 006302 Processing audio with plugin 'Lisp.dll'

- 00295424 006302 Wrote 0 frames to F:\Vic\Desktop\MrsWatson-Report-Tue-May-----------------\utterance_deessed.wav

Am I doing something wrong? How hard would this be to fix/implement?

Solved issue by reverting Mrs.Watson version to one used in npm module node-vst-host.
