even tried with docker can't find suitable replacement.

Couldn't find debug
Perhaps you meant @debug, @enum, big or detach
  No documentation found.

  Binding debug does not exist.

Use the @debug macro to print debug output.

You have to enable debug output for you to actually see it. You can enable it with the env variable JULIA_DEBUG:

julia> @debug "hello"

julia> ENV["JULIA_DEBUG"] = "all"
"all"

julia> @debug "hello"
┌ Debug: hello
└ @ Main REPL[4]:1
