Link to issue: [TINKERPOP
2751](https://issues.apache.org/jira/browse/TINKERPOP-2751)
If a transaction is attempted on a graph that does not support transactions,
the client hangs as it waits for a response from the server. The change in this
PR handles that case and responds to the client with a
`transactionNotSupported()` exception.
Ideally, we would want the client to fail at `transaction.begin()` but this
would involve a much bigger change on the server and across the GLVs. For now,
users should be notified that they need to use a transaction-enabled graph when
attempting to perform a graph operation (rollback or commit)

> Key: TINKERPOP-2751
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2751
> Project: TinkerPop
> Issue Type: Bug
> Components: javascript, server
> Affects Versions: 3.6.0
> Reporter: Stefan Templin
> Priority: Minor
> Labels: Transaction
>
> Hi,
> I am trying to get transactions working for a while now, but no matter what i
> do, i can't get the transaction to commit.
> h3. My Setup:
> * Running gremlin-server 3.6.0 in Docker on localhost using the
> default-configuration.
> {code}
> version: '3.7'
> services:
> gremlin:
> image: tinkerpop/gremlin-server:3.6.0
> container_name: gremlin
> restart: always
> ports:
> - "8182:8182"
> {code}
> * Javascript-Gremlin-lib 3.6.0
> h3. Problem:
> Im executing the following code:
>
> {code:js}
> const dc = new DriverRemoteConnection('ws://localhost:8182/gremlin', {
> 'rejectUnauthorized': false});
> const g = traversal().withRemote(dc);
> const tx = g.tx();
> const gtx = tx.begin();
> try {
> await gtx.addV('person').iterate();
> await gtx.addV('software').iterate();
> await tx.commit();
> // stuck here
> console.log('here')
> } catch (err) {
> await tx.rollback();
> } finally {
> await dc.close();
> }{code}
> The code just will never get past 'await tx.commit()', no error, nothing. It
> just hangs up there. The code before that is properly executed and the Graph
> contains both vertices.
> Am I doing anything wrong there, or are transactions not working properly?
> Hope you can help me with that.
>
> Kind regards,
> Stefan
