Cannot read properties of undefined (reading 'startConnecting')

[akosyakov]

After upgrading 1.8.17 we see lot of

TypeError: Cannot read properties of undefined (reading 'startConnecting')
    at /app/node_modules/@grpc/grpc-js/src/load-balancer-pick-first.ts:308:43
    at processTicksAndRejections (node:internal/process/task_queues:78:11)

We tried to downgrade a bit to 1.8.8 but it still happens from time to time.

Can you check if the same thing happens with version 1.9.0?

[svenefftinge]

I believe it can potentially still happen as the code is executed on next tick and there's a on of other code pathes potentially being executed that would potentially change/clear the children property.
So I'd say either capturing the children array in the lambda or checking for undefined would be important.

The fix for this has been published in version 1.9.1.
