Subject: [PATCH] Fix headerToToken value check from null to undefined

`headerToToken` returns `Promise<string | undefined>`. However, the existing
check assessed `headerToToken().then(value => value === null ? something
: somethingElse)`.
This should never be true.
Instead, this check is replaced with `!value`.
