while mime_types was a string, resp_mime_types is a vector of strings. If I am not mistaken it contains all matching mime types ordered by probability. Unfortunately I am not able to find proof for this in the documentation. However, to fix your issue you could loop through the vector or just use the first element resp_mime_types.

Subject: [Bro] Duqu script
I tried to test the bro script to log the Duqu attack published through Github. The broctl check failed and here below the output :
"error in /usr/local/bro/share/bro/policy/bro-scripts/duqu.bro, line 81: no such field in record (HTTP::c$http$mime_types)"
I've understood that $mime_type has changed in the new bro version and I've tried to change it in the script with "resp_mime_types" . Here below the new output :
error in /usr/local/bro/share/bro/base/protocols/http/./entities.bro, line 27 and /usr/local/bro/share/bro/policy/bro-scripts/duqu.bro, line 81: pattern requires string index (vector of string and /^?(image\/jpeg)$?/)
I am new to bro scripts. Please, I need your help to understand how to manage this kind of errors. Anyone could help please ?
Please find below the link to the original script :
