I have nifi 11.4 and solr 7.4. I wanted to create a pipelines where nifi reads files from a folder and indexes them on solr using tika (https://solr.apache.org/guide/7_4/uploading-data-with-solr-cell-using-apache-tika .html). if I try to index a pdf file through the command line everything works but if I try to do the same thing with nifi I get the following error:
error adding field 'stream size' = 'null' msg = for input string null
the nifi flow is as follows
where am i wrong?
thanks for support
