[yamishav]

Fix for:
On

const type = Reflect.getMetadata('design:paramtypes', object, method)[index];

An error can be thrown if the index is not in the array;

Thanks! Can you add a test case to demonstrate the error?

Also please run yarn format so that we get rid of the whitespace changes in the diff.

[yamishav]

Hi, I updated the yarn format.
Regarding the test, we are having a complex senior where we auto-generate the endpoints so it's a little complex to reproduce the bug on a test
In this case, the reflection has issues handling the getMetadata and the index is trying to access a out of index in the array

[epiphone]

Ok, I'll look into adding a test and getting this merged his week.

[yamishav]

any updates?

[yamishav]

Hi, Any chance we can move on with the PR?

[epiphone]

Okay, please revert the lock file deletion and we'll get this merged!

[epiphone]

The reason I'm a bit hesitant merging this is it's unclear to me whether this is something we should handle in the library or is this an edge case specific to your particular setup and thus better handled in your codebase. Hard to say without knowing the context or having a test!

Then again it should be a pretty non-intrusive change so might as well go for it, I think.

[yamishav]

ok. I have reverted it

[epiphone]

Your previous commit added a bunch of .idea/ files, let's get rid of those eh?
