Xml Push failure.

I am currently operating Zanata on a local server. The version uses 4.5.5 and the following error occurred while pushing the translation file for 4.5.0 .

[INFO] Found source documents:
[INFO] l_AchievementEventMessageEn_vi-VN
[WARN] pushType set to 'Trans': existing translations on server may be overwritten/deleted
[?] This will overwrite existing TRANSLATIONS on the server.

Are you sure (y/n)? y
[ERROR] Operation failed: org.zanata.rest.dto.resource.TranslationsResource cannot be cast to org.zanata.rest.dto.resource.Resource

To retry from the last document, please set the following option(s):

--from-doc "l_AchievementEventMessageEn_vi-VN"

.
