For consistency checking your datastore check out Mark's great blog post.

What kind of import process did you abort how? If it was batch-inserter, then there are no guarantees on consistent stores if you abort it and you'll probably safer redoing your import.
If it was transactional there shouldn't be inconsistencies.
Please also note that 2.1.0 had some issues and shouldn't be used, so you might run into double issues there.

Why does this where query no longer work properly for ShopifyAPI?

I am trying to do a simple where query on both the Checkout class and Order class via the REST ShopifyAPI, but it keeps returning inaccurate data.
Here are two examples:
[12] pry(main)> Order.count
=> 9
[13] pry(main)> Order.where(created_at: (Time.now - 1.minute)..(Time.now)).count
=> 9
[14] pry(main)> Order.where(created_at: (Time.now - 1.second)..(Time.now)).count
=> 9
[15] pry(main)> Order.first.created_at
=> "2021-05-15T02:59:36-05:00"
[16] pry(main)> Order.last.created_at
=> "2021-04-23T02:43:44-05:00"
And the same thing for Checkout:
[8] pry(main)> Checkout.where(created_at: (Time.now - 24.hours)..(Time.now)).count
=> 6
[9] pry(main)> Checkout.where(created_at: (Time.now - 10.minutes)..(Time.now)).count
=> 6
[10] pry(main)> Checkout.where(created_at: (Time.now - 1.minute)..(Time.now)).count
=> 6
[11] pry(main)> Checkout.count
=> 6
[18] pry(main)> Checkout.first.created_at
=> "2021-04-29T00:13:16-05:00"
[19] pry(main)> Checkout.last.created_at
=> "2021-05-15T03:00:37-05:00"
What could be the cause of this?
Edit 1
Strangely enough, this issue seems to not show itself when I try another model like Product:
[28] pry(main)> Product.where(title: "High Coverage Foundation").count
=> 1
[29] pry(main)> Product.count
=> 6
That's the correct feedback I was expecting. I am expecting something similar for the Order model too, but for some reason it isn't working properly.
I have restarted my local terminal session, and reinstalled my Shopify-api-cli...to no avail.
Edit 2
See more examples from both classes that show the existence of those objects which indicates that the query should work.
[51] pry(main)> Order.first.id
=> 3779683877046
[52] pry(main)> Order.last.id
=> 3741986750646
[53] pry(main)> Order.first.created_at
=> "2021-05-15T02:59:36-05:00"
[54] pry(main)> Order.last.created_at
=> "2021-04-23T02:43:44-05:00"
[55] pry(main)> Checkout.first.id
=> "ef8dd57a1b1911da9077df7789698847"
[56] pry(main)> Checkout.last.id
=> "7133c7aeb0ff3b4b506c2a66e4190ee3"
[57] pry(main)> Checkout.first.created_at
=> "2021-04-29T00:13:16-05:00"
[58] pry(main)> Checkout.last.created_at
=> "2021-05-15T03:00:37-05:00"
Edit 3
So it seems that it works for queries done on attributes that have a string, but not an integer and datetime is inconsistent:
[79] pry(main)> Order.where(cart_token: '36e017f94cbf19bee298d61334b68225').count
=> 1 // #RIGHT
[80] pry(main)> Order.where(created_at: '2021-05-15T02:59:36-05:00').count
=> 9 // #WRONG
[81] pry(main)> Order.where(current_total_price: 294.14).count
=> 9 // #WRONG
[82] pry(main)> Order.where(email: 'alex#test.com').count
=> 1 // #RIGHT
[83] pry(main)> Order.where(processed_at: '2021-05-15T02:59:35-05:00').count
=> 3 // #RIGHT STRANGELY ENOUGH
[97] pry(main)> Order.where(processed_at: '2021-05-15T02:59:35-05:00').first.id
=> 3779683877046 // #RIGHT
[98] pry(main)> Order.where(processed_at: '2021-05-15T02:59:35-05:00').last.id
=> 3779668639926 // #RIGHT

I got a response on Shopify's official forum which can be seen here.
TL;DR, Shopify's rubygem doesn't implement ranged dates exactly like ActiveRecord does, they use created_at_min and created_at_max attributes on the model.
So the correct query for the ShopifyAPI for that where query is:
ShopifyAPI::Order.where(created_at_min: Time.now - 6.days, created_at_max: Time.now).count

original_transaction_id is not coming while validating Apple receipt after Successful IAP

Unable to know the reason for the response "This tracking number cannot be found. Please check the number or contact the sender"

I found that the fedex tracking id that I was testing was real, and the credentials that I was using for fedex tracking api were of test/sandbox type not production.

I am using neo4j-community-2.1.2 and neo4jphp. Is there any work around to this?

You will probably fix your overflow issue if you tune the JVM settings to your data. This page in particular deals with it but the entire "Configuration and Performance" setting is crucial reading for anyone using Neo4j.
But with that in mind, I'd try to avoid queries like this. The fact that this type of indexing is referred to as "legacy" should be a warning and, in general, I find it's best to avoid it completely if there are better options out there. Legacy indexing, as far as I can tell from everything I've read, does not let you take advantage of labels, so you're missing out on one of the most useful aspects of Neo4j 2.0+.
The presence of that asterisk suggests you want a full-text search against an index. Legacy indexing is the only way to do that natively, but the compromise is a massive query like this. Ignore the index for a moment and you can see how you'd do it if you weren't using legacy indexes. Since there are a lot of nodes that all have something in common, you could put a label on them and then search against the label. That'd be as easy as this:
MATCH (n:`MyLabel`) WHERE n.name =~ "abc*" return n
Even with an index on MyLabel:name, the regex search would skip it and do it in Cypher, but it's so much easier to read, manage, and it is the modern way of searching the database.
The alternative, which I use whenever I need fulltext search, is Elasticsearch. It uses lucene indexes, same as Neo4j. The plugin I linked in the comment, https://github.com/sksamuel/elasticsearch-river-neo4j, will index the properties of given labels in your database. You can search against that and it will return the nodes that match. The downside to this is that it's extra plumbing and I'm not sure how efficient it is -- it says that it updates all nodes on every scrape of the database, which doesn't seem great but it's a start and I'm sure it could be improved -- BUT you have the benefit of not resorting to outdated features or clunky queries to get the information you need. I see you're using PHP, so you may be able to write a script that handles it more efficiently at an app level.
TL;DR: Tune your server to fix the crash; fix your query and your indexes to simplify your code.
