The BLAST command stops with an error.

Hi all.

I would like to evaluate the assembly quality by running BLAST to the fasta file output by Trinity.
I ran the command as follows, but this job was stopped with an error message.

$ ~/miniconda3/envs/py27/bin/blastx 
-query /home/nkarim/avenae/trinity_even_out_dir/Trinity.300.longest.fasta 
-db /home/nkarim/blast/db/nr 
-outfmt 6 
-evalue 1e-3 
-out /home/nkarim/blast/output/avenae.out

Error: NCBI C++ Exception:

I’m working on a Linux environment using miniconda.
I found some people having similar errors, but they seemed to be having Windows specific errors.
What could be wrong with my command?

Thank you very much for your help!
