Cant fetch collection data on a new channel

Describe the bug

On fetching the products i a collection, I get the following error Vendure logs

[run:worker] error 12/21/20, 1:37 PM - [RpcExceptionsHandler] error.no-price-found-for-channel[run:worker] Error: error.no-price-found-for-channel

[run:server] error 12/21/20, 1:37 PM - [Vendure Server] {"status":"error","message":"Internal server error"}

To Reproduce

1. Create a new channel
2. Add some products with facetvalues
3. Create a new collection and filter it by a particular facet value
4. Try to retrieve the content of the collection

Expected behavior I expect to get the contents of the channel

Environment (please complete the following information):

• @vendure/core version: Vendure dev (next branch)
• Nodejs version: 12.20
• Database (mysql/postgres etc): Postgres

You’ll need to follow the migration guide to upgrade: https://www.vendure.io/blog/2020/12/announcing-vendure-v0.18.0/#breaking-changes--migration-guide

My bad, I thought this issue was the channel deletion issue. Let me try this out. Also, I updated from 0.18.0 to 0.18.1, so think I need not follow the migration guide?
