Accept header priority ignored by conneg\n\n**Line 142:**\n```javascript\n'Accept': 'application/ld+json, text/turtle, application/json'\n```\n\nJSS conneg returns `text/turtle` even when `application/ld+json` is listed first. When Turtle is returned, the keys are separate nodes not linked from `#me` via `cert:key`, causing verification to fail.\n\n**Fix:** Change to `'Accept': 'text/html'` to get the HTML with embedded JSON-LD.\n\n### 2. JSON-LD regex too strict\n\n**Line 160:**\n```javascript\n/\u003cscript\\s+type=[\"']application\\/ld\\+json[\"']\\s*\u003e([\\s\\S]*?)\u003c\\/script\u003e/i\n```\n\nThis regex expects the `\u003e` immediately after the type attribute (with optional whitespace). It fails when there are additional attributes like `id=\"me\"`:\n```html\n\u003cscript type=\"application/ld+json\" id=\"me\"\u003e\n```\n\n**Fix:** Use more flexible regex:\n```javascript\n/\u003cscript[^\u003e]*type=[\"']application\\/ld\\+json[\"'][^\u003e]*\u003e([\\s\\S]*?)\u003c\\/script\u003e/i\n```\n\n### 3. @id references not dereferenced\n\nThe code in `extractCertKeys` looks for `cert:key` on the `#me` node and passes each key object to `parseKeyObject`. However, if `cert:key` contains `@id` references like:\n```json\n\"http://www.w3.org/ns/auth/cert#key\": [\n  { \"@id\": \"#key1\" },\n  { \"@id\": \"#key2\" }\n]\n```\n\nThe `parseKeyObject` function won't find `cert:modulus`/`cert:exponent` because they're on the referenced nodes, not inline.\n\n**Workaround:** Add inline modulus/exponent to the key references in the profile.\n\n**Proper fix:** Dereference `@id` pointers to find the actual key objects in the JSON-LD graph.\n\n## Environment\n\n- JSS v0.0.75\n- Node.js v22.21.1","author":{"url":"https://github.com/melvincarvalho","@type":"Person","name":"melvincarvalho"},"datePublished":"2026-01-09T12:54:57.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/70/JavaScriptSolidServer/issues/70"}
