Upload catalog translation causes an error

リンクされたドキュメントにある upload catalog と invoice translation のエントリポイントから始め、報告された呼び出しを InvoiceResource.java と LocaleUtils.java に沿って追跡します。ドキュメント化されたフローで upload を再現し、fr_FR のような locale が末尾のスラッシュ付きで LocaleUtils に到達しなくなり、報告された Invalid locale format エラーも発生しないことを確認します。

The upload catalog translation and upload invoice translation code causes the following error:

org.killbill.billing.client.KillBillClientException: Invalid locale format: fr_FR/

The following stack trace is seen in the Kill Bill logs:
