Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/checkout@v4, actions/setup-dotnet@v4, actions/upload-artifact@v4. Actions will be forced to run with Node.js 24 by default starting June 2nd, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true. For more information see: https://github.blog/changelog/2025-09-19-deprecation-of-node-20-on-github-actions-runners/

The type name JsonColumnizer conflicts in whole or in part with the namespace name 'JsonColumnizer'. Change either name to eliminate the conflict. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1724)

Change the type of parameter 'uriString' of method 'IFileSystemPlugin.GetLogfileInfo(string)' from 'string' to 'System.Uri', or provide an overload to 'IFileSystemPlugin.GetLogfileInfo(string)' that allows 'uriString' to be passed as a 'System.Uri' object (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1054)

Change the type of parameter 'uriString' of method 'IFileSystemPlugin.CanHandleUri(string)' from 'string' to 'System.Uri', or provide an overload to 'IFileSystemPlugin.CanHandleUri(string)' that allows 'uriString' to be passed as a 'System.Uri' object (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1054)

In externally visible method 'string TextValueSpanExtensions.GetText(ILogLine logLine)', validate parameter 'logLine' is non-null before using it. If appropriate, throw an 'ArgumentNullException' when the argument is 'null'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1062)

In externally visible method 'string TextValueSpanExtensions.GetText(IColumn column)', validate parameter 'column' is non-null before using it. If appropriate, throw an 'ArgumentNullException' when the argument is 'null'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1062)

Non-nullable property 'Parent' must contain a non-null value when exiting constructor. Consider adding the 'required' modifier, or declaring the property as nullable, or safely handling the case where 'field' is null in the 'get' accessor.

Nullability of type of parameter 'obj' doesn't match overridden member (possibly because of nullability attributes).
