Regex / How to access a specific group?

Graylog Central (peer support)

Hello,

I use a rule to extract a string from another string using regex. This is working, writing the result to a field shows “{“0”:”“Info”}". But how can I access the value of the group 0 (in this case “Info”)?

This one is not working
set_field(“my_prio”, to_string(my_field[“0”]));

Working now when writing to another field with set_field(“my_prio”, to_string(my_field[“0”]));
Writing to the same field which was used for the object before is not working as the data type is different.
