Hello, we are facing an issue described at apache/apisix#7349. Please advise on how to add the nginx parameter during deployment via the Helm chart:

http:
  lua_shared_dict:
    prometheus-metrics: 10m

After adding via customLuaSharedDicts:, I encountered the following error:

[emerg] 1#1: the size 536870912 of shared memory zone "prometheus-metrics" conflicts with already declared size 10485760 in /usr/local/apisix/conf/nginx.conf:100

The reason for adding the parameter is increasing errors in the apisix_nginx_metric_errors_total metric:

It has also been noticed that when a certain number of errors is reached, the metrics stop displaying correctly.
