When importing data from 20.07 to 20.11, the following error is reported

Yes!The data is exported successfully, but an error is reported when dgraph live is used.When I specify schema, I report the following error:

./dgraph live -f ../export/dgraph_data/export/dgraph.r37173781.u0115.0929/g01.rdf.gz -s ../export/dgraph_data/export/dgraph.r37173781.u0115.0929/g01.schema.gz -a localhost:9080 -z <zero_ip>:5080

So I first use pydgraph set schema, and then use the following command to import the data:

./dgraph live -f ../export/dgraph_data/export/dgraph.r37173781.u0115.0929/g01.rdf.gz -a localhost:9080 -z <zero_ip>:5080

my cluster is ok
