Log collection panics when using with options

[iliazlobin]

Problem statement

When using the log collection feature with option blocks of different types it panics.

Steps to reproduce

In an empty directory, create a file echo.variant that resembles an example with the following content:

option "bool-opt" {
  default     = false
  description = ""
  type        = bool
}

option "string-opt" {
  default     = "default-value"
  description = ""
  type        = string
}

job "echo" {
  parameter "message" {
    type = string
  }

  exec {
    command = "echo"
    args = ["text=${param.message}"]
  }
}

job "echotest" {
  step "first-step" {
    run "echo" {
      message = "{\"a\":\"b\"}"
    }
  }

  log {
    collect {
      condition = event.type == "run" && can(event.run.job == "echo")
      format = "run=${jsonencode(event.run)}"
    }
    file = "${context.sourcedir}/log.txt"
  }
}

Run echotest job and receive an error:

panic: inconsistent map element types (cty.String then cty.Bool)
