AddFeature api failing with error -2147219879

Trying to add features on Arc Enterprise to a feature service. Code not working so trying to sort issue in the addFeature GUI for the service. The json for the attributes validates: Check it values against domain, field length etc. All we get is:

{
 "error": {
  "code": 400,
  "extendedCode": -2147219879,
  "message": "Unable to complete operation.",
  "details": [
   "Unable to perform addFeatures operation."
  ]
 }
}

No documentation for the error that we can find. Any ideas? Surely the error codes are known somewhere.
What is being pasted into the Attributes box:

[

"datasource": "Basher et al. (2011); Basher et al. (2018)",
