Error message

Missing params "repo" make sure you pass the parameters in URL

What it means

MissingParamError thrown by fetchRepo when username is present but reponame is falsy. Reached only after the first two guards pass (so username is truthy and the combined check was false). The constructor reports only "repo" as missing with urlExample as the secondary message.

Solutions

1. Add the repo: /api/pin?username=<owner>&repo=<name>.
2. Validate that repo is a non-empty string before requesting.

Example fix

// before
// GET /api/pin?username=anuraghazra

// after
// GET /api/pin?username=anuraghazra&repo=github-readme-stats

function requireRepo(repo) {
  if (!repo || typeof repo !== "string") {
    throw new Error("repo is required: /api/pin?username=OWNER&repo=NAME");
  }
}

const isNonEmptyString = (v) => typeof v === "string" && v.trim().length > 0;

When it happens

Trigger: A request like /api/pin?username=anuraghazra with no repo. Both earlier guards pass (username is truthy, and the combined !username && !reponame check is false because username exists), so control reaches the reponame-only check at line 76.

Common situations: A URL template that interpolates the owner but omits the repo segment; a truncated copy-paste; or a generator that resolved the owner but not the repo slug.
