ChildProcessCrashedError for Angular project

[alexvaidya]

Question

I am trying to configure Stryker for Angular UI project. Stryker is running fine locally. But, when trying to run from circleci pipeline, we are getting error: "ChildProcessCrashedError: Child process [pid 2688] exited unexpectedly with exit code null (SIGKILL). Last part of stdout and stderr was:" Does anyone has any idea how to resolve this issue?

Stryker environment

+-- @stryker-mutator/core@8.0.0
+-- @stryker-mutator/xxx-xxx@x.x.x

+-- karma@6.3.0
+-- angular-cli@13.3.0

Additional context

Here is a log message from circleci:
