error obtaining absolute path of the chaincode: %s

Error message

error obtaining absolute path of the chaincode: %s

What it means

When the parsed path has no scheme (treated as a local filesystem path), ValidatePath converts it to an absolute path with filepath.Abs. If that conversion fails (rare; e.g. working directory issues), this error wraps the cause.

Solutions

  1. Ensure the process has a valid, existing working directory before calling
  2. Pass an already-absolute path so filepath.Abs needs no cwd resolution
  3. Restart the process from a valid working directory

Example fix

// before
os.Chdir("/tmp/deleted-dir") // cwd removed
err := platform.ValidatePath("chaincode/node/mycc")
// after
err := platform.ValidatePath("/opt/chaincode/node/mycc") // absolute path
Defensive patterns

Strategy: validation

Validate before calling

if _, err := os.Getwd(); err != nil { return errors.New("invalid cwd; pass absolute paths") }

Try / catch

if err := platform.ValidatePath(rawPath); err != nil && strings.Contains(err.Error(), "error obtaining absolute path") {
    // retry with an absolute path
}

Prevention

When it happens

Trigger: ValidatePath called with a scheme-less path while filepath.Abs fails — typically because os.Getwd fails, e.g. the current working directory was deleted or is inaccessible.

Common situations: Process started in a directory that was subsequently removed (common in containers/CI); running with a deleted cwd; extremely long paths exceeding system limits.
