Complete logs

[c-bordon]

I was able to detect where these messages are generated in the log, it is due to the file:
src/core/server/opensearch_dashboards_config.js

This file is edited by us to search for the loadingLogos to S3 and the title of the application is also defined:

      loadingLogo: _configSchema.schema.object({
        defaultUrl: _configSchema.schema.string({
          defaultValue: 'https://s3.amazonaws.com/warehouse.wazuh.com/stack/dashboard/Symbol.png'
        }),
        darkModeUrl: _configSchema.schema.string({
          defaultValue: 'https://s3.amazonaws.com/warehouse.wazuh.com/stack/dashboard/Symbol-3.png'
        })
      }),
      faviconUrl: _configSchema.schema.string({
        defaultValue: '/'
      }),
      applicationTitle: _configSchema.schema.string({
        defaultValue: 'Wazuh'

If we leave this file as it comes by default, the logs increase:

,"branding"],"pid":7751,"message":"logo default config is not found or invalid."}
,"branding"],"pid":7751,"message":"mark default config is not found or invalid."}
,"branding"],"pid":7751,"message":"loadingLogo default config is not found or invalid."}
,"branding"],"pid":7751,"message":"favicon config is not found or invalid."}
,"branding"],"pid":7751,"message":"applicationTitle config is not found or invalid. Title length should be between 1 to 36 characters."}

This is the default file:

    branding: _configSchema.schema.object({
      logo: _configSchema.schema.object({
        defaultUrl: _configSchema.schema.string({
          defaultValue: '/'
        }),
        darkModeUrl: _configSchema.schema.string({
          defaultValue: '/'
        })
      }),
      mark: _configSchema.schema.object({
        defaultUrl: _configSchema.schema.string({
          defaultValue: '/'
        }),
        darkModeUrl: _configSchema.schema.string({
          defaultValue: '/'
        })
      }),
      loadingLogo: _configSchema.schema.object({
        defaultUrl: _configSchema.schema.string({
          defaultValue: '/'
        }),
        darkModeUrl: _configSchema.schema.string({
          defaultValue: '/'
        })
      }),
      faviconUrl: _configSchema.schema.string({
        defaultValue: '/'
      }),
      applicationTitle: _configSchema.schema.string({
        defaultValue: ''
      })

I am investigating how to skip these messages

[c-bordon]

I was investigating a little more, these messages are of the INFO type, and they do not represent an error in the application, in fact, all the resources are loaded correctly, to be able to omit these messages it is necessary to touch the application code, which would not enter in the scope of this release.

These validations are performed in the following file:
https://github.com/opensearch-project/OpenSearch-Dashboards/blob/1.2.0/src/core/server/rendering/rendering_service.tsx#L346
