Convert failed - convert: Bogus "StripByteCounts" field

[keatre]

Describe the bug
When issuing a scan from the WebGUI - the scanner is found, and I scan the image - but the system errors out on the convert command.

To Reproduce
I can call 'convert' manually using the same parameters to the TIFF file, and it errors out as well:

keatre@vmhdd:/usr/lib/scanservjs$ /usr/bin/convert data/temp/~tmp-scan-0-0001.tif -scale 868 -background '#808080' -extent 868x1583-0-0 data/preview/preview.tif

convert: insufficient image data in file `data/temp/~tmp-scan-0-0001.tif' @ error/tiff.c/ReadTIFFImage/1671.
convert: no images defined `data/preview/preview.tif' @ error/convert.c/ConvertImageCommand/3258.

@keatre, your error is similar to mentioned in #406 and #445. In these issues the bogus StripByteCounts tag of the TIFF files is causes the same output error as yours during convert procedure. In the mentioned issues the problem was associated with the bad HP driver, that corrupts TIFFs (and some other file formats too). So, probably, something similar happens due to your Epson FF-680W. One of the suggested ways was to suppress the convert errors (1,2).

You can try the commands like
sudo su --shell /bin/bash - scanservjs --command 'scanimage --mode Color -x 215.9 -y 299.7 --format png --resolution 300 > test.png
sudo su --shell /bin/bash - scanservjs --command 'scanimage --mode Color -x 215.9 -y 299.7 --format tiff --resolution 300 > test.tiff
to check whether your problem is only with tiff format or not.
