Instead of throwing the error, perhaps want to throw it to next like this so it can be handled by the error handler.

The problem is that your id is of type string instead text: ""STRING" has an affinity of NUMERIC, not TEXT.". When I insert those large values sqlite3 seems to store them as floating points instead of text. Floating points have limited number of digits it can store accurately.

Swap your Low and High in ElseIf and Else.

Please, use the proper indentation next time. The code is hard to read when it is not formatted properly.

This issue is very simple to solve and you should look into const, let and var and their respective differences.

Instead of using a conditional operator, you could also use a single pattern by placing 7(\D*\d){12} and 1(\D*\d)11} in an alternation, as the start and the end of the pattern are the same.

If you don't need the value of the capturing group afterwards, you can turn it in to a non capturing one using (?:

I suspect that in the second part, this 11} should be a quantifier like {11}

The pattern could look like:

As per comments I understand, that you want to return a true Observable, if the response.checkData value is included in the pageUid array.

You can do the following:

Edit: consequences added

I have replaced your exec with eval to get rid of your global variable (still not good coding practise, but if this is what you need...). Also, the for is not needed.

PS: the variables i, v and c should have better names.

Default parameters are a nicety of C++. You need to pass two arguments if you're calling outside C++.

Update: I managed to figure out the issue.

In particular cases, the convolution results in an r, g or b value > 1.0. That representation cannot work.

My current solution is to limit the convolution to 1.0 (if it exceeds). I am not currently solving for values < 0.0 but that is trivial.
