AtoM 2.10.1 index issues

[Braydon Justice]

When attempting to install the new 2.10.1 version of AtoM I get an error during the create search index step of the symfony install script. It seems that the default mappings use a parameter that is not compatibile with the 7.x version of elasticsearch that AtoM 2.10.1 requires. I am trying to upgrade a 2.8 instance of AtoM but that shouldn't matter since I am using a blank database and I deleted the index before upgrading (something that should be mentioned on the upgrade page since attempting to upgrade without deleting the index causes elasticsearch to fail to start).

Here is the error:

Mapping definition for [pt] has unsupported parameters:  [include_in_parent : false] [reason: Failed to parse mapping [_doc]: Mapping definition for [pt] has unsupported parameters:  [include_in_parent : false]]

Thanks in advanced for any input or recommendations that anyone has.

Cheers,

Braydon
