the response post request error page.

is there way can file post request or missing something?

according logs seems fine on both cases (the controller runs until return request in both cases)

content on responseentity when post request:

201 created,[b@1e6804c8,{content-type=[application/docx], content-disposition=[form-data; name="attachment"; filename="archivo.docx"]} 

content on responseentity when request:

201 created,[b@39cb5a1a,{content-type=[application/docx], content-disposition=[form-data; name="attachment"; filename="archivo.docx"]} 

i have not found error message.

changing accept header on post request fixed problem. not sure why problem since lists */ * (ignore space, don't know how comment display correctly) last option, removing application/json , text/plain solved issue
