In @x/provider/handler/server_test.go:
- Around line 1-33: The file ends without a final newline causing a formatting
lint failure; run gofmt (or add a trailing newline) on the test file so the file
containing TestErrorGRPCStatusCodes and references to handler.ErrInternal is
terminated with a newline character (i.e., ensure the file ends with a blank
line) and re-run static checks.

In @x/provider/handler/server.go:
- Line 82: The build fails because server.go returns
types.ErrInternal.Wrap("NOTIMPLEMENTED") but the symbol types.ErrInternal is
undefined; fix by either (A) replacing that reference with an existing error
value or constructor used elsewhere (e.g., the project-wide internal error
constant/function) or (B) defining ErrInternal in the types package with the
same error type/shape expected here (and ensuring the Wrap method is available
or using the appropriate error-wrapping utility). Update the return in the
handler in server.go to use the correct existing error symbol or add ErrInternal
to the types package so the Wrap call compiles.
- Line 63: The error is caused by using sdkerrors.Wrapf(types.ErrInternal, ...)
and by types.ErrInternal being undefined; change this call to the same
method-syntax used elsewhere: use types.ErrInternal.Wrapf("err: %v", err). Also
ensure that the types package defines and exports ErrInternal (or import the
correct package that provides ErrInternal) so the symbol compiles; keep the
wrapping style consistent with the other usages (lines using
types.ErrInternal.Wrapf).
- Line 42: The code references types.ErrInternal which no longer exists; update
the call to use the correct error symbol and import (for example replace
types.ErrInternal.Wrapf(...) with sdkerrors.ErrInternal.Wrapf(...) and add the
import "github.com/cosmos/cosmos-sdk/types/errors" aliased as sdkerrors), or
alternatively replace the call with a local/internal error helper (e.g.,
fmt.Errorf or your package's ErrInternal) so the undefined types.ErrInternal is
removed; ensure the change is made where server.go returns nil,
types.ErrInternal.Wrapf(...) and adjust imports accordingly.
