It seems like extraLimitsConfig is expecting a value of type String but I want to provide:

    extraLimitsConfig:
      readline_rate_enabled: true
      readline_rate: 1000
      readline_burst: 2000

Helm chart version: 6.16.5 App version: 3.0.0

Can someone suggest how I can get this working? Appreciate the help!

Hi ns0092,

try setting the extraLimitsConfig as follows:

extraLimitsConfig: |
  readline_rate_enabled: true
  readline_rate: 1000
  readline_burst: 2000

This should work
