Trying to load air-routes.graphml yields no such file or directory

I wanted to use the air routes database to write up a question that I need to ask, but I can't seem to follow the instructions found in Practical Gremlin and at https://github.com/krlawrence/graph/blob/master/sample-data/load-air-routes-graph.groovy#L13 to load the air-routes database

@Valentyn Kahamlyk does gtx....iterate() have a strategy for maintaining the order of these writes?

Is this an acceptable way of making sequential writes? I am using async.retry to retry the promise returned by tx.commit(), similar to this example from Amazon: https://docs.aws.amazon.com/neptune/latest/userguide/lambda-functions-examples.html#lambda-functions-examples-javascript ``` const tx = g.tx(); try { // get the graph traversal source from the transaction const gtx = tx.begin();
gtx.addV("owner").property(id, "1111").iterate() gtx.addV("laptop").property(id, "macbookAir2024").property("yearReleased", 2024).iterate() gtx.V() .hasLabel('laptop') .has(t.id, textP.startingWith(partialMacbookId)) .order() .by('yearReleased', desc) .limit(1) .as("mostRecentMacbook") .mergeE( new Map([ [t.label, 'hasOwner'], [direction.out, merge.outV], [direction.in, merge.inV]] ) ) .option(merge.outV, .select('mostRecentMacbook')) .option(merge.inV, .V(ownerId)) .iterate(); return tx.commit(); } catch (error) { logger.error(error); // roll back the transaction return tx.rollback(); }

.mergeV() with Javascript not working

The solution was to allow neptune to use the default mimetype; removing the mimetype header solved the issue

Yes that's certainly true, for reasons of breaking up a series of several long .mergeV() and .mergeE()'s I want to use a transaction so that there's space in between.

I'm using Tinkerpop 3.6.2, where .concat() and .format() weren't yet added, and I'm using Neptune where lambdas aren't supported
