Hi All,

I'm trying update an existing index using PUT/my\_index/\_mapping.

But i'm unable to do so, error encountered:  
"type": "action\_request\_validation\_exception",  
"reason": "Validation Failed: 1: mapping type is missing;"

Did anyone got this fixed?  
Using elastic 6.3.2.

Thanks

What exactly are you sending when you get that error?
