[9.1.4] Elastic-agent doesn't gather tls info with synthetics integration

Hello!

Recently I updated my cluster and all of the Elastic-agents from 8.17.4 - - → 8.19.4 - - → 9.1.4 (and then updated a couple of agents to version 9.1.5 just for test) and it appeared that they stopped gathering (at least stopped importing to corresponded index) such fields as tls.* with synthetics integration

After I discovered the problem, i decided to reinstall agents with same latest version. it didn’t take an effect. that i rolled back my agent with synthetics integration to version 8.17.4 and it started gathering info. then i decided to check which version brings this problem and I started to update to almost each version one by one starting from 9.0.0

my longest path was 8.1.7.4—>9.0.0-→9.0.8-→9.1.0-→9.1.1-→9.1.2-→9.1.3-→9.1.4 and it broke here
