  1. On the Source code part of the dump, on line 87 you can see the system is verifying if USER_AGENT_INFO-VERSION is a floating point number:
    |   86|* rule for "(Chrome, >= 8.0, *)"
    |>>>>>|  if user_agent_info-browser eq 'Chrome' and is_float( user_agent_info-version ) eq abap_true.
    |   88|    lightspeed_info-supported = abap_true. "#EC NOTEXT 
    
  2. On the chosen variables section, you can see USER_AGENT_INFO-VERSION has some extra information and therefore cannot be interpreted as a number:
    |ME->USER_AGENT_INFO-VERSION
    |    537.36 Google Favicon
    |    333233246666624676666
    |    537E3607FF7C5061693FE
    |    000000000000000000000
    |    000000000000000000000
