**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser):
opensearch v 2.7.0
chrome 113.0.5672.127
**Describe the issue** :
hello,
i have few error during navigation:
- Refused to execute inline script because it violates the following Content Security Policy directive: “script-src ‘unsafe-eval’ ‘self’”. Either the ‘unsafe-inline’ keyword, a hash (‘sha256-75XtnrpDA0UHDMcl7S8lvswryIOd0RqgacRh0AMOgdk=’), or a nonce (‘nonce-…’) is required to enable inline execution.
- uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘split’)
have you some documentation about web server’s configuration to fix this issues.
thanks

While back I see something like this here. Note sure if this is the same type of issue.
