Invalid path: ' '.

Error message

Invalid path: '${id}'.

What it means

The module id resolution utility (util.js resolveIdRelative) normalizes relative ids ('.' and '..' segments) against a base id. When a '..' segment tries to go above the root of the base id (baseIds.pop() returns undefined), the path cannot be resolved and OperationInvalidError is thrown.

Solutions

1. Fix the relative id so '..' segments do not exceed the base path depth.
2. Use an absolute module id (e.g. 'my/package/sub/module') instead of a deep relative path.
3. Validate the resolved path depth against the base before calling the resolver.

Example fix

// before
resolveIdRelative('../../foo', 'pkg/mod'); // throws
// after
resolveIdRelative('./foo', 'pkg/sub/mod');
// or use absolute id
resolveIdRelative('pkg/sub/foo');

var ups = (id.match(/\.\.\//g) || []).length;
var depth = baseId ? baseId.split('/').length : 0;
if (ups >= depth) throw new Error('Relative id escapes base: ' + id);

function isResolvableRelativeId(id, baseId) { return typeof id === 'string' && (id.charAt(0) !== '.' || (baseId && (baseId.split('/').length > (id.match(/\.\.\//g) || []).length))); }

try { resolved = util.resolveId(id, baseId); } catch (e) { if (/Invalid path/.test(e.message)) { resolved = defaultModuleId; } else throw e; }

When it happens

Trigger: Resolving an id like '../../some/module' against a base id with too few path segments, e.g. base 'pkg/module' with '../..' — popping the last segment leaves nothing to pop.

Common situations: Hand-written relative AMD/requirejs module ids with excess '../' segments; config or plugin descriptors referencing modules relative to the wrong base; typos after refactoring module paths.
