{"tag":"delayed_job","free":"Job error: #<Errno::ENOENT: No such file or directory @ rb_sysopen - /app/db/sphinx/production/ts-listing_delta.tmp>","type":"error","structured":{"payload":"#<ThinkingSphinx::Deltas::DelayedDelta::DeltaJob:0x00007f2bfff43eb8 @index=\"listing_delta\">"}}

I'm using Heroku run flying-sphinx rebuild to setup.

if i try

heroku run rake ts:index, it says sh: 1: indexer: not found

heroku run rake ts:start it says Riddle::NoConfigurationFileError: '/app/config/production.sphinx.conf' does not exist, however heroku run rake ts:configure succeeded.

stack: heroku-22, Rails 6, delayed job.

Please guide me to solve it.

thanks.
