# 53120:  Invalid Recording Rule(s)

Log Type: APPLICATION

Log Level: ERROR

## Description

Raised by the server when a Recording Rule is invalid.

### Possible causes

* An empty set of rules \[] is not allowed.
* A rule containing all must have a value of true and must not contain any other expression.
* A rule must contain a type field.
* If kind is used, it must be audio or video.
* A maximum of 20 recording rules are allowed per room.

### Possible solutions

* Ensure the set of rules has at least one rule.
* If you include all in a rule, the only other allowed field is type.
* Ensure every rule has a type field.
* Ensure kind is one of the valid enum values.
* Limit the number of recording rules to 20 or fewer.
