Julius Feature Vector Length Error

Hello all,
I am using a slightly modified version of the sample English recognition network (Recognition_en.m) provided at https://www.hark.jp/networks/samples-hark-2_2_0.tar.gz.

I am using the following nodes [parameters]:
MelFilterBank ->
MSLSExtraction ->
Delta [FBANK_COUNT = 13] ->
FeatureRemover [SELECTOR = <Vector<int> > (an empty vector)] ->
SpeechRecognitionClient

I have Julius running separately and the traffic from HARK to Julius appears to be sent correctly. However, I get the following error:

........................................................................................................................................................................................................Stat: server-client: connect from 127.0.0.1
forked process [27700] handles this request

input name function was called
source_id = 6, azimuth = 9.999267, elevation = 0.000000, sec = 1611531646, usec = 391823
mfc_read() : cnt(112) <> size(192)
read_count < 0, read_count=-3, veclen=96
ERROR: FEATURE_INPUT plugin: fvin_read() returns error (-2)
### Recognition: 1st pass (LR beam)

Has anyone seen this error before, and do you have any advice for how to fix it?

Thank you!
JD
