What version of typescript are you running this with?

I also ran into the same problem as @Cristiandi. Please fix this.

P.S. The version of TypeScript that I am using is 4.0.3.

[kayotimoteo]

Same problem here TypeScript version 4.0.3.

[imnotjames]

We aren't currently using 4.0 yet - perhaps there's a compatibility feature we didn't enable for the latest release?

Looks like the issue was introduced in the type definitions as of Typescript 3.7 - https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html - because there's a problem with overriding properties with accessors.

And for some reason our build wasn't using this until 0.2.27 - not sure the cause there, as we should have been updating over time.

If we drop to Typescript 3.6.0 it should fix this issue - but it does mean that TypeORM as a project is stuck on that until whenever we can create a breaking change. What a pain. :|

[imnotjames]

This should be fixed as of 0.2.28
