http: improve error message with null header #46048
Description
Which @angular/* package(s) are relevant/related to the feature request?
No response
Description
When a header value of an HTTP call is null we throw a TypeError: Cannot read properties of null (reading 'length').
That's accurate and could be more useful if we also specify the header with null value.
You can find a reproduction on StackBlitz.
Based on a discussion on Twitter here.
Proposed solution
Throw an error Cannot read the "length" property of the header "bar" because it has value null
Alternatives considered
Stricter typings of the headers so that we can show a type error.

Oh please, a big yes to this! This was a bug I came across like 6 months ago and it was a really pain in the neck to debug (value was null for some users not all).
