Expected "${str}".

Error message

Expected "${str}".

What it means

Angular's UrlParser parses a serialized URL string token by token; this is the generic expectation helper that throws when the next characters of the remaining string do not match the syntactic element the parser needs (a delimiter like '/', '(', ')', ':' or a segment) — i.e. the URL string is malformed for the router grammar.

Solutions

1. Fix the malformed routerLink or URL string that fails to parse
2. Check for unbalanced parentheses in auxiliary outlet syntax and missing outlet names
3. Avoid manually constructing URLs with characters reserved by the router grammar; use router.serializeUrl
