Errors while updating full text search index

Seafile Server
,
#1

Pro Seafile Server, v7.1.4. While doing:

/opt/seafile/seafile-server-latest/pro/pro.py search --update

I get these error messages for I think every .doc file

06/04/2020 02:07:54 [INFO] seafes:172 extract: extracting d4658fc1-13dd-471f-aa59-111acc0dad67 /Documents/status reports/status_080221.doc...
Error: Unable to access jarfile /opt/seafile/seafile-server-latest/pro/python/seafes/poi/ExtractText.jar
06/04/2020 02:07:54 [ERROR] seafes:176 extract: failed to extract /Documents/status reports/status_080221.doc: [Errno 32] Broken pipe

I checked my install. The directory

/opt/seafile/seafile-server-latest/pro/python/seafes/poi/

exists, but has no ExtractText.jar in it.

#2

same problem here with Seafile Pro 7.1.8

… took it from http://54.154.102.253/seafile-server-latest/pro/python/seafes/poi/ExtractText.jar
(seems to be an unprotected Server)
