*tesseract executable problem:*
for TESSDATA_PREFIX you use a path with space and you did not not escape it
properly. That is why you get an error about an existing file
("C:\Program/eng.traineddata").
Solutions:
a) use path without speciation characters like space
b) learn how to properly escaped path to environment variables
When you solve this problem you will face the same problem (Error, OSD
requires a model for the legacy engine) as with node-tesseract-ocr (that
seems to take care about handling paths correctly) ;-)
I guess problem is that OSD needs legacy engine while you restrict
tesseract to use only LSTM engine. So you need to fix your option to allow
usage of legacy engine. I am not sure if OSD needs also eng.traineddata
with legacy components, but you will see.
