Hi @Shicheng_Guo,
I am guessing you took this snippet from our documentation. The response is indeed empty because the tractability was not up-to-date with the latest changes - tractability
no longer has an id.
This is the correct request:
query target($ensemblId: String!){
target(ensemblId: $ensemblId){
id
approvedSymbol
biotype
geneticConstraint {
constraintType
exp
obs
score
oe
oeLower
oeUpper
}
tractability {
label
modality
value
}
}
}
We have corrected the documentation, and the changes will be shortly available. Thanks for reporting!
