: 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.

: Changeio.Writer
tobytes.Buffer
to avoid type check issues.This change addresses the type check warning effectively by ensuring that
stdout
andstderr
are always non-nil, which avoids potential nil pointer dereferences when used later in the code.
279-280
: Check for errors instderr
before proceeding.This is a robust error handling practice. Checking
stderr
before 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

280-280: undefined: ErrPortForwarding (typecheck)
A small refactor on
PortForwardPod
function. 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.Writer
object withnil
