AEP schema creation error - "Cannot merge incompatible data types"

Hi, thanks for reading.

 

I was using my org's AEP sandbox to validate a mobile app PoC.

 

To do this I needed to create a AEP schema, but upon trying to create a schema, I get the following error:

 I also found that I cannot edit my previously created schemas as well.

 

Any advice on how to resolve this issue would be greatly appreciated.

 

Thanks

I am not too familiar with the XDM schemas, but this looks like a type mismatch...

 

It seems that the schema may be looking for a datetime stamp? Perhaps the app is sending as string? Maybe this is a simple as casting the string as datetime before applying to the schema?

 

I am guessing there is already data coming into the schema in that field which may be preventing it from being edited?

Adding to what Jennifer already shared w.r.t. the data types, you might also wanna check the below scenarios.

- There could be the same field defined in your tenant by someone else with a different data type. Please try renaming the Field name(not the Display name) with correct data type as required.

- You will not be able to edit your previously defined schema that has been used in the Platform if you're trying to bring in a breaking change. However, you should be able to do so if data is not yet ingested into that schema.

Here is a link from the documentation explaining the supported and breaking changes to an XDM schema  - https://experienceleague.adobe.com/docs/experience-platform/xdm/schema/composition.html?lang=en#evol...
