Hi dev team, I got this bug error since update 24.1.0, when create new gcpr dgraph client and send query to Dgraph, it will the error

there is my example query

}

this error cause both from the UI ratel and Dgraph java client. Of course we can handle it by retry, but it will slower our process.

while that alpha container will throw this error
