KSeF concurrent export limit reached

So lautet die Ablehnung wörtlich: „[KSEF-21182] The KSeF 2.0 API rejected your invoice export request because the authenticated entity already has the maximum number of concurrent exports in flight. The message returned is "Osiągnięto limit trwających eksportów" (concurrent export limit reached).“

KSeF 2.0 enforces a per-context ceiling on the number of simultaneously running invoice-export operations (POST /invoices/export, /invoices/export/async and related endpoints). Once the ceiling is hit, further export requests return HTTP 429 with body code 21182 until at least one running export finishes. The limit is per authenticated entity — not per token — so opening more tokens does not raise the ceiling.
