Anticipated errors & fixes

401 "invalid key"

Cause: API key or token is wrong.

Fix: Regenerate both fresh from trello.com/power-ups/admin.

404 on a valid-looking list/card ID

Cause: The token was generated without access to that board (private board you're not a member of).

Fix: Make sure you're a member of the board, and regenerate the token while logged into that account.

401 "Unauthorized: Invalid API key."

Cause: Your eConnect Authorization header is missing, malformed, or the key was regenerated/revoked.

Fix: Copy your api_key fresh from the eConnect dashboard and confirm the header reads exactly "Authorization: Bearer <key>".

429 "Too many requests"

Cause: You've exceeded your plan's per-minute rate limit.

Fix: Wait a minute and retry, or upgrade your plan for a higher per-minute limit.

429 "Monthly API limit exceeded"

Cause: You've used your plan's full monthly request allowance.

Fix: Wait for your next billing cycle reset, or upgrade to a plan with a higher monthly limit.
