{"error":{"code":400,"message":"Unable to complete operation.","details":["Unable to perform applyEdits operation."]}}
We had the same error show up and the problem seemed to be stemming from the feature class being m-aware without the necessary attributes.
Might not always apply to everyone having a this problem, but that was the issue for us.
Hi
I had the same problem yesterday, and I was able to apply edits to few of my feature layers successfully and 2 of them I couldn't and I got the same message. Although my post request on the firebug status show 200 status, but the JSON response text in firebug
shows unable to apply edits. I think, I almost figured out the problem. The problem is with the particular feature class in the geodatabase and it is non-versioned. It is worth opening the featureclass in Arcmap and start editing the featureclass, if it shows the featureclass is non-versioned, then you cannot apply edits.
Please try this and let me know whether you are successful.
I will investigate from my side and let you know once successful.
Regards
Ganesh
