Eclipse crash when a mapping downloaded from the CE version is open in OnPrem version

fosto

For a customer who is migrating from on premise version 13.3 to the CE, we are trying to use the MeC Mapping M3EDI_M3EDISalesOrderAcknowledge_Sync_Out_2_13_0 downloaded from the CE in eclipse on premise 13.3.
Unfortunately while opening it in Eclipse we get the following error message
ERROR 2025-01-31 15:19:14,880 MeCModelHandler Failed to load MeC model. Reason is JAXBException unexpected element (uri:"", local: "Standard"). Expected elements are <{}Name>,<{}Layout>,<{}Description>,<{}SchemaIn>,<{}File>,<{}ID>,<{}Namespace>,<{}ChangeDate>,<{}Version>,<{}SchemaOut>

Any idea?

Many thanks in advance!

You can get a old version of the Mapping or open the file with notepad+ and correct the problem. Try find whe word "Sandard".

Is not this mapping from a more recent version of MEC?
