Workflow Testing Framework violates typescript checks? "duplicate name 'ActivityHeartbeat' in Namespace coresdk"

Hello, I’m trying to run a simple workflow test and I find that there are linting and typescript errors when using the @temporalio/testing module.

So far, I’m faced with two issues and this post is about the second issue. The first issue is Workflow Testing Framework violates typescript checks? @temporalio/worker/lib/connection").NativeConnection is not assignable to type @temporalio/testing/node_modules/@temporalio/worker/lib/connection").NativeConnection

This topic’s issue is the error “duplicate name ‘ActivityHeartbeat’ in Namespace coresdk" when trying to execute my simple workflow test.

FAIL test/workflows/my-workflow.test.ts
  ● Test suite failed to run

    duplicate name 'ActivityHeartbeat' in Namespace coresdk

Any advice is appreciated. Thank you!

Same as in your other post, this is due to having multiple copies of packages. In this case, its about @temporalio/proto. Possibly because you import different versions @temporalio/* packages.

Just to close the thread on this issue as well…

The problem was that I installed the temporal packages right in-between upgrades so some were on 1.7 while others were on 1.8.
