We get an error of the Elasticsearch by saving a BusinessObject over the ivy.repo with a field of type Map< String,String >.

Elasticsearch update index of document failed because of: {"root_cause":[{"type":"illegal_argument_exception","reason":"mapper [details.data.Value1] of different type, current_type [text], merged_type [date]"}],"type":"illegal_argument_exception","reason":"mapper [details.data.Value1] of different type, current_type [text], merged_type [date]"}

The problem ist clear. The field "details.data.Value1" is a date field and i try to store a String.

But the definition of our BusinessObject is different to that!
The field "data" of the "detail" object is defined as a Map< String,String >.
We get this error when we run the following code in an IvyScript (we used a helper class for Maps, because IvyScript is not able to handle double generics).

JobDetail detail = new JobDetail();
Helper helper = new Helper();
helper.setParam("Value1", (new Date()).toString());
detail.data = helper.getParams();
job.details.add(detail);

detail = new JobDetail();
helper.setParam("Value1", "foo");
detail.data = helper.getParams();
job.details.add(detail);

Why does Elasticsearch change the given attribute to a date field, although we just fill in String values?
Furthermore we defined the value as a Map of Sting-String value pairs.
Is there a solution of this issue?

We decided not to use JSON objects instead of our Map, because of the easy handling in further uses.

Hi Adrian

As it looks like Elasticsearch converts the result of ch.ivyteam.ivy.scripting.objects.Date.toString() automatically into a Date type. As much as I know it is not possible to turn off this auto-conversion, most of the time it is a useful feature.

To avoid this problem you have two possibilities:

  1. Overwrite the Elasticsearch template and redefine the field as String type.
  2. Don't use the ch.ivyteam.ivy.scripting.objects.Date but the java.util.Date class. Elasticsearch doesn't recognize the format in toString() automatically - or you can write your own Date output format with SimpleDateFormat (which goes into the same direction).

I recommend solution 2.
