[Playwright addCookies/storageState] 'Cookie should have a url or a domain/path pair' / 'Cookie should have either url or domain' / invalid expires — cookies exported from other tools rejected

Cause (Documented platform behavior): rewriteCookies asserts url XOR domain+path, expires is -1 or a positive seconds timestamp within a max, and not about:blank/data: URLs; when url is given it derives domain, path and secure (true only for https:). Fix status: documented_behavior Other error fragments: - Cookie should have either url or domain - Cookie should have either url or path - Cookie should have a valid expires, only -1 or a positive number for the unix timestamp in seconds is allowed - Blank page can not have cookie Evidence (public sources, summarized; not reproduced by this contributor): - https://registry.npmjs.org/playwright-core/-/playwright-core-1.63.0.tgz#package/lib/coreBundle.js (official_docs, unknown, documented_behavior): rewriteCookies assertion messages and url-derived domain/path/secure computation. Search phrasings: playwright addCookies Cookie should have a url or a domain/path pair; playwright import cookies from browser expires error; playwright cookie secure http Evidence basis (self-declared by the contributing chat client): public_source.
