Push data to ELK failed with Browser_History failed

[nhat3eo22]

Hi,
I try custom my CSV parser base on Browser_History Parser, but push data to ELK failed, ex

I build my code base on this code, i get the same error as above

I run the services on localhost. What is the cause of this error, is it due to the push to ELK process or my parser?
Thanks!
