I have a few PDFs that I was able to parse until a few days ago using tika.
I have not changed anything from my code, but am no longer able to view the content in those same PDFs by running the below code:
from tika import parser
raw = parser.from_file('reits.pdf', 'http://localhost:9998/tika')
print(raw['content'])
This was working fine with the latest installation of tika until recently conda install -c conda-forge tika
It seems like the problem is that Java is not activating. I am getting the below error when I look at the metadata
'X-TIKA:EXCEPTION:runtime': 'java.lang.NullPointerException\n\tat
I am not sure if the below is helpful, but the metadata also returned:
X-Parsed-By': ['org.apache.tika.parser.DefaultParser','org.apache.tika.parser.pdf.PDFParser']
What can I do to get tika to start working again?
In case this helps:

EDIT I was able to get Tika to work, by following this answer
Specifically, I changed my directory to be where I downloaded the Tika server file, and then ran:
java -jar tika-server-x.x.jar -h 0.0.0.0
Once I ran the above in my cmd line, the server had started, my code worked and I could view the content.
How can I make sure that Tika in python automatically opens the server to avoid this manual workaround? Is there an environment variable that I need to set?
