The explanation is in the error :

I wondered if I can execute multiple update queries in parallel

No. A single connection only supports sequential execution of queries. node-postgres doesn't stop you from issuing multiple calls at once, but it does queue them internally, so you won't get any benefit from creating all promises at once and calling Promise.all on them.

_{(That said, I don't know how Knex transaction works, if it uses a connection pool it might not actually limit you to a single connection. However, that is not a best practice if you serve multiple HTTP clients, you should use only connection per HTTP request.)}

The issue exists because the inline assembly assumes the first argument as well as the return value to be using register eax, which is true for Delphi in 32-bit mode as per Delphi's calling convention (and although the inline assembly documentation states that there shouldn't be made any assumptions about registers other than ebp and esp, this always held true even inside of inline assembly statements when they were placed at the top of a function).

However, 64-bit mode uses a different calling convention in which the first argument is in rcx and the return value is using rax. So here you are getting random uninitialized garbage as return value that happened to be in that register (with its bytes swapped) because it's never explicitly set.

The best, portable solution would be to implement the byte swap in pure Pascal without inline assembly:

I'm not able to understand why. Can someone help me?

That if conditionally enables a validation. Your to_id is the same as from_id and so to_id is not validated at all. But even if it was, to_id has a value, so there wouldn't be an error from this field.

Overall, I'm not quite sure why are you expecting a validation error here or what that error should be. In my experience, assertions like assert_not @model.valid? are virtually useless. The record might not be valid because of unrelated reasons and you'll have no idea. Personally, I assert the exact error message I'm expecting. Something along these lines (rspec syntax)

You need to install ContentNegotiation plugin for deserializing JSON data to a BookRequest object and if you use kotlinx.serialization then mark the BookRequest class with Serializable annotation. Here is the full example:

...have 0 records in tblGetAsk

This means that there is no matching row in tblGetAsk for that userEmail of tblUser, so your condition should be where G.userEmail IS NULL:

/(?=TITLE: )/g seems like a reasonable start. I'm not sure if the gutter of 2 characters whitespace is in your original text or not, but adding ^ or ^ to the front of the lookahead is nice to better avoid false-positives, i.e. /(?=^TITLE: )/mg, /(?=^ TITLE: )/mg or /(?=^ *TITLE: )/mg.

You can try something like this. Basically enumerate the dictionary values and use it's index to access the books array.

The issue here is that you only have a single dimension array for starring, and so when multiple values are added for one movie and the assumption is later made that each movie only has one actor, the program thinks that it is meant to be for the next movie. What you should do is create a string inside of the loop and then append the actor names and a comma to that string, like so:
