Subject: [PATCH] Check for outboundStreamOpts before accessing it

This method should be the same as the others in regards to checking for valid property.
It seems the extra logic for `isElectron` evaded the correct checking when calling from an incoming stream.

Error reported:
TypeError: Cannot read properties of undefined (reading 'publisherProperties')
```
