Invalid marketplace name: "${marketplace}"

Error message

Invalid marketplace name: "${marketplace}"

What it means

The marketplace segment of buildPluginId failed isValidNameSegment: it must be 1–64 characters, lowercase alphanumerics with internal dots/hyphens, no leading/trailing dot or hyphen, and no `@` (which would break the `name@marketplace` ID format). This indicates the marketplace identifier supplied to the ID builder is malformed — usually from a hand-edited or generated marketplace registry name.

Solutions

1. Fix the marketplace name in the config/catalog to a valid slug: /^[a-z0-9]([a-z0-9.-]*[a-z0-9])?$/, ≤64 chars.
2. Normalize programmatically (lowercase, strip invalid chars, trim edge dots/hyphens) before calling buildPluginId.
3. Guard with isValidNameSegment(marketplace) before building and report a config error to the user naming the offending marketplace entry.
4. If the marketplace identifier legitimately contains uppercase or underscores (e.g. an org name), mint a separate lowercase slug field for it.

Example fix

// before
const id = buildPluginId("my-tool", "Acme Market");
// after
const id = buildPluginId("my-tool", "acme-market");

if (!isValidNameSegment(marketplace)) {
	throw new Error(`Marketplace name must match /^[a-z0-9]([a-z0-9.-]*[a-z0-9])?$/ (1-64 chars, no "@"): "${marketplace}"`);
}

function isMarketplaceName(v: unknown): v is string {
	return typeof v === "string" && /^[a-z0-9]([a-z0-9.-]*[a-z0-9])?$/.test(v) && v.length <= 64 && !v.includes("@");
}

let id: string;
try {
	id = buildPluginId(name, marketplace);
} catch (err) {
	if (err instanceof Error && err.message.startsWith('Invalid marketplace name')) {
		throw new Error(`Fix the marketplace entry "${marketplace}" in your plugin config: lowercase slug required.`);
	}
	throw err;
}

When it happens

Trigger: Calling buildPluginId(name, marketplace) with an empty marketplace string, one longer than 64 chars, containing uppercase/underscores/spaces/`@`, or a value like `my-market-` (trailing hyphen) or `Corp Market` (space).

Common situations: A user's marketplace config file has a marketplace key like `Work_Marketplace` or an empty name field; tooling derives the marketplace name from a URL (leaving `github.com` with slashes/dots in wrong places) or from a display label; marketplace renamed and old capitalized names remain in config.
