hydrate undefined error for multiple paths on direct deploy

[kenhorn]

Describe the issue
./node_modules/@architect/hydrate/src/hydrate.js:123
if (lambdaHasManifest && lambda.config.runtime.startsWith('nodejs')) {
^
TypeError: Cannot read properties of undefined (reading 'runtime')
at ./node_modules/@architect/hydrate/src/hydrate.js:123:46

v10.10.3

If my app.arc contains two paths for a single source dir, ie:

/foo
method post
src src/http/post-foo

/foo-noauth
method post
src src/http/post-foo

I get the above error for direct deploys, but a normal deploy is fine. The lambda object has no config member, as in the above scenario it's an array of configs. Presumably something isn't calling .flatten() or similar for direct deploys.

Removing the second path's setup works as a workaround in dev.

Steps to reproduce
Steps to reproduce the behavior:

1. Go to '...'
2. Click on '....'
3. Scroll down to '....'

Expected behavior
A function should be deployed per normal / full deploy
