Exception - "The schema must include an 'allOf' attribute..." when creating a schema

[Ahmer Khan]

Hi, I'm trying to create a schema using aepp and am getting the following exception.
` 474 raise TypeError("Expecting a dictionary")
475 if "allOf" not in schema.keys():
--> 476 raise Exception(
477 "The schema must include an ‘allOf’ attribute (a list) referencing the $id of the base class the schema will implement."
478 )

Exception: The schema must include an ‘allOf’ attribute (a list) referencing the $id of the base class the schema will implement.`

I am creating the schema by running getSchema in a different sandbox and then importing it into another one by using createSchema. I made sure the field groups and other dependencies pre-exist in the new sandbox.

Any ideas on how I can get the allOf attribute that is needed to create the schema?

Hi @arkster you need to reference the field Groups (Mixins) and classes from the new environment in that key.

https://experienceleague.adobe.com/docs/experience-platform/xdm/api/schemas.html?lang=en#create

"allOf": [
        {
            "$ref": "https://ns.adobe.com/xdm/context/experienceevent",
            "meta:xdmType": "object",
            "type": "object"
        },
        {
            "$ref": "https://ns.adobe.com/_mytenant/mixins/5924ad9758d080a4c5e7d4493c0356646a38f828d000c98b",
            "meta:xdmType": "object",
            "type": "object"
        },
        {
            "$ref": "https://ns.adobe.com/_mytenant/mixins/27c9589e21afa8a84d2b2aff9e7e4dddf566e209d8158fe2",
            "meta:refProperty": [
                "/_mytenant/userID"
            ],
            "meta:xdmType": "object",
            "type": "object"
        }
    ],

I think it might be also helpful to post the code you are executing.

Hello @arkster
For some reason I am discovering the issue and @benedikt-buchert actually answered it perfectly.
The allOf is a default parameter that contains the reference to the fieldgroups you want to use in the schema creation.
While this issue is dated, I am closing it.
Feel free to re-open it with additional information.
