Cypress test logs in Team City are too verbose - teamcity

Question

We are running Cypress tests in Team City and the output of the tests is crazy verbose. When I run the tests on the agent machine directly I don't see such verbose logging so it might be because of Team City.
Small sample (there are thousands of these):
cypress:https-proxy Making intercepted connection to 60378
cypress:server:server Got UPGRADE request from /__socket.io/?EIO=3&transport=websocket
cypress:server:timers queuing timer id 5 after 85000 ms
cypress:server:timers child received timer id 5
cypress:server:socket socket connected
cypress:server:timers clearing timer id 5 from queue { '3': { args: [], ms: 30000, cb: [Function: timeoutTimeout] }, '5': { args: [], ms: 85000, cb: [Function] } }
cypress:server:timers queuing timer id 6 after 85000 ms
cypress:server:timers child received timer id 6
cypress:server:timers clearing timer id 6 from queue { '3': { args: [], ms: 30000, cb: [Function: timeoutTimeout] }, '6': { args: [], ms: 85000, cb: [Function] } }
cypress:server:timers queuing timer id 7 after 85000 ms
cypress:server:timers queuing timer id 8 after 1000 ms
cypress:server:timers clearing timer id 8 from queue { '3': { args: [], ms: 30000, cb: [Function: timeoutTimeout] }, '7': { args: [], ms: 85000, cb: [Function] }, '8': { args: [], ms: 1000, cb: [Function: timeoutTimeout] } }
cypress:server:timers child received timer id 7
cypress:server:timers child received timer id 8
Any ideas?

Those are Cypress' own debug messages - they are only logged in case the DEBUG environment variable is set to a matching pattern, i.e. * or cypress:*. They are not related to the teamcity logger.
Either override the env.DEBUG Build Parameter in your Build Configuration and set it to an empty string, or (in case there's something else in your build that needs it to be set to *) unset it just at the launch inside your build step, like
env -u DEBUG npm run cypress -- --reporter teamcity
