Unused type cause error ?

result = [] of Hash(String, String | Int64) (working)
result = [] of Hash(String, String | Int32 | Int64) (error)

I've failed to compile your code.
Don't you have a reproducable example? This is usually done by removing unnecessary lines and dependencies from example until error stop to appear.

[codenoid]

yes sir, but why unnecessary lines made error, and i think should not

[konovod]

To answer the question we (at least me) need a short piece of code, e.g. one that can be run on https://carc.in/ and see an error.
Your code has too much dependencies, it is difficult to understand what is an error.
Without short self-sustainable code example chances that the error will be fixed or even found are low. So it would be a lot of help if you can remove unnecessary lines and dependencies one by one (but error still must appear, that's the point. If it stopped appearing - return the line you just deleted and try deleting another ones). I understand that it can be difficult and take quite a some time, but without it the error will likely remains not fixed.

lltry sir

[mig-hub]

@codenoid it does not look like the result associated with the code provided. In your code somevar is always nil because you never use a query parameter called "sv". Therefore it should immediately return an empty result array as json. So it can never print "success", not even once.

I'll close this as invalid until we get some code we can run and reproduce the error.
