CosmosDBIn binding broken

[zsolt-halo]

This is a Bug Report

Description

Breaking PR: https://github.com/serverless/serverless-azure-functions/pull/399

• What went wrong? The following binding config in the serverless.yml results in "Binding not supported" error message during packaging.

• cosmosDB: x-azure-settings: collectionName: SomeCollection connectionStringSetting: ConnectionString databaseName: SomeDatabase direction: in id: "{id}" name: id partitionKey: "{id}"

  
  There are 3 types of cosmosDB bindings:

1. cosmosDB with direction in which should yield "$cosmosDBIn_displayName"
2. cosmosDB with direction out which should yield "$cosmosDBOut_displayName"
3. cosmosDBTrigger with direction in (direction is obvious here) which should yield "$cosmosDBTriggerIn_displayName"

The above mentioned PR broke the cosmosDBIn binding config by replacing it with the comsosDBTriggerIn.

IMPORTANT: Please note that the current beta version 1.0.2-19 has a feature to download the latest bindings.json from here which will result in breaking any changes we make to the current bindings.json.

Also interestingly in the referenced bindings.json the cosmosDBIn_displayName and cosmosDBOout_displayName bindings are not present at all.

Their corresponding "new names" with the same configuration options are:

• documentDBOut_displayName
• documentDBOut_displayName

However I think that bindings.json is referencing some legacy stuff.

I have only started diving into this project a few days ago so sorry if I don't understand some hidden knowledge :) please let me know if I'm wrong somewhere.

I'll do PR to fix the cosmosDBIn issue.

• What did you expect should have happened? It should have been translated to a proper binding in the function.json
• What was the config you used?

• cosmosDB: x-azure-settings: collectionName: SomeCollection connectionStringSetting: ConnectionString databaseName: SomeDatabase direction: in id: "{id}" name: id partitionKey: "{id}"

• What stacktrace or error message from your provider did you see? The error is generated by: node_modules/serverless-azure-functions/lib/shared/utils.js line 91 because the generated bindingDisplayName is not among the ones being parsed from the bindindgs.json file.
