# system.util.jsonEncode(system.tag.getConfiguration()) exceeds maximum recursion depth / why can't we export MQTT Tag Configuration?

This is unexpected but a known issue that we've already got logged.

The workaround on the ticket is to cast each of the dictionaries returned in the `getConfiguration` result to string before passing to `system.util.jsonEncode`.

```auto
result = system.tag.getConfiguration(PathToTag)
print system.util.jsonEncode(str(result[0]))

```

What are you hoping to achieve in the end? You aren't going to be able to create or modify MQTT tags by importing whatever you manage to export. They are managed by the MQTT modules.
