source record is not a vertex

Expected behavior and actual behavior

I am using the script sql command in the console to run a batch query that selects a Person vertex then selects an Email vertex and then creates an edge HAS from person to email. When I run the command I get the following error.

Error: com.orientechnologies.orient.core.exception.OCommandExecutionException: Error on execution of command: sql.create edge has from $user to $email

Error: java.lang.IllegalArgumentException: source record is not a vertex

Steps to reproduce the problem

orientdb {db=test}> script sql
[Started multi-line command. Type just 'end' to finish and execute]
orientdb {db=test}> begin
orientdb {db=test}> let user = select from person where uid = '12345'
orientdb {db=test}> let email = select from email where email = '[e-mail]'
orientdb {db=test}> let edge = create edge has from $user to $email
orientdb {db=test}> commit
orientdb {db=test}> return $edge
orientdb {db=test}> end

Important Questions

As far as I know both Person and Email are vertexes in the database. The data and schema was inserted using a .graphml database exported from neo4j. What is source record here ? the person ? Why is it not being treated as a vertex ? Another thing I would like to point out is for the same records if I directly create an edge using the records’ rid’s, the edge between the vertexes are successfully created.

@amyth

that is because $email is from update.

try with select on email or use

let email= update  email set email = '[e-mail]' return after @this where email = '[e-mail]'

Can you check in the schema if Person has V as superclass ?
