72-72: Address multiple undefined errors reported by static analysis.The static analysis tool has identified numerous instances where variables and functions are used but not defined within the visible scope of the code. This could indicate missing imports, typos, or logical errors in the code structure. Each instance needs to be verified and corrected to ensure the code is functional and error-free.

273-273: Changeio.Writertobytes.Bufferto avoid type check issues.This change addresses the type check warning effectively by ensuring that
stdoutandstderrare always non-nil, which avoids potential nil pointer dereferences when used later in the code.
279-280: Check for errors instderrbefore proceeding.This is a robust error handling practice. Checking
stderrbefore proceeding ensures that any errors during the port forwarding setup are caught early, preventing further execution when the setup is already known to be faulty.Tools

A small refactor on
PortForwardPodfunction. It needs more refactor in future, however this PR suggests a small change to avoid having type check warning as the old code tried to compare anio.Writerobject withnilSummary by CodeRabbit
