hi, i want to know how bulk loader api do to avoid this exception, cause i want to write another api to load the exported rdf data. any ideas?

the data are like this:
<:uid35b3869> “777000636”^^xs:int . <:uid35b38ef> “777002156”^^xs:int . …

it’s obvious that we have already had uid, but when i mutate this data, it causes the above exception.

how to let the dgraph to accept the uid ?

i have some ideas, but the dgraph server had exception: UNAVAILABLE: Channel in TRANSIENT_FAILURE state. it means the server is down

It looks like you’re using UIDs which are not handed out by Dgraph. You might be using unallocated UIDs (which you created), or you might have deleted Dgraph Zero’s folder.

ip:6080/assign?what=uids&num=N, You should now N=0，Make N larger, N=10000000.
