TypeError: Cannot redefine property: $map

I’ve been asked to do some fixes on a project I developed with Claudia. I’ve tried to deploy them and I get the above error:

> claudia update
> updating REST API
> [TypeError: Cannot redefine property: $map]

I’ve had a look in the source (both Claudia and my own app) and can’t find anything that this might reference. I’ve tried to go back to 1.2.0, the last version I used to deploy successfully with no luck.

Locally I’m using node v4.4.1, although remove version is using node 4.3 (but I would not expect any major compatibility).

As an aside, one thing that might be useful is when there is an error to do the following:

console.log(error.stack)

As the stack is being swallowed up and only the error.message is being shown.

I have fixed this issue in pg-promise and released v.4.3.1.

It no longer uses custom array methods like $map, etc. And you should have absolutely no problem loading the library as many times as you need, it is not a non-reentrant library 😉

I will be updating pg-promise to stop using $map and methods like that. Will provide an update when finished.
