val sensitiveHeader = "sensitive"

basicRequest
  .get(uri"http://google.com")

  .send(

      logRequestBody = true,
      sensitiveHeaders = Set(sensitiveHeader),
      beforeRequestSendLogLevel = LogLevel.Info
    )
  )

Output:

[run-main-0] INFO sttp.client3.logging.slf4j.Slf4jLoggingBackend - Sending request: curl \
  --request GET \
  --url 'http://google.com' \
  --header 'sensitive: NOT IGNORED' \
  --location \
  --max-redirs 32

Expected: header "sensitive" is not logged.

Actual: header "sensitive" is logged.
