_gremlinQuerySource.V<V1>().Where(filter).ToArrayAsync() fails when the record exists & How to get Gremlin script correctly from .Debug()

[Robert Green]

Describe the bug
I am trying to use the call await _gremlinQuerySource.V<V1>().Where(filter).ToArrayAsync();. Sometimes it works, sometimes it doesn't. It is inconsistent.

filter is a Expression<Func<V1, bool>>.

I'm simply looking for a name (i.e., "Customer - (test #123)")

This is how I'm calling this method:

await _unitOfWork.CustomerRepository.GetVertexAsync(x => x.name == customer.name);

so, filter is x => x.name == customer.name

... it doesn't error, it just returns [0] when there is a record there.

The query I use in the graph (Cosmos Gremlin Db) g.V().hasLabel('Branch').has('name', containing('(test #')). Would be nice if you can also tell me how to generate this specifically.

But I still want eyes on my issue. I'd like to be able to query the Db using the filter expression.

This led me to wanting to debug the issue.

So, I then tried:

var a = _gremlinQuerySource.V<V1>().Where(filter).Debug();

but this returns:

and not the actual gremlinq script itself. Can you help with this too?

Expected behavior
I expect to get the data from the graph but instead I get nothing.

Sample
I'm at work, for a corporate client. Trying to implement your technology. I don't have the time to breakdown and build up a sample. If it is a really really must, I guess so... IDK how/when... but I can tell you I am blocked... Major corporation, trying to get Exram into Production!

We are in UAT and a particular feature needs my code to work. Of course I can just write the script (ugly Cosmos Gremlin Code) itself and be done in 30 minutes but that will kill my case for Exram. (which I currently have in many services for my team)

Your guys call... (hope you guys can help me/us)

So, you guys actually have a bug, maybe you can use your code to verify.

But, when the filter is x => x.name == "Customer - (test#123)" it fails.
But, if I say filter is x => x.accountNumber == "12345" it works.

So, if you can please answer the Debug() question. But there is defintely a bug here if the string has ( or ) or #. One of those is breaking your .Where(..):

TSelf Where(Expression<Func<TElement, bool>> predicate);
