I am in the process of re-implementing the `cloudantStorage` code that was originally written for IBM Cloud to use the new Cloudant SDK. It's mainly working, but I'm having problems with flow encryption.

To do this, I am implementing the Storage API. The first time I run Node-RED with Cloudant Storage enabled it creates the database as expected and creates and saves the flow credential. The problem I get is that when I stop and re-run Node-RED it fails to load the previously saved credentials with a syntax error. However, I have put a console log into the new `getCredentials` function and it's not even being called. Is it possible that there's a problem in the core which is causing this?

Clearly the standard local filesystem storage works fine, it just seems to appear when there's a pluggable storage module added.

I am looking in `@node-red/runtime/lib/storage/index.js` and it appears to me that the call for `getCredentials` is commented out from `StorageModuleInterface`. Is this correct @knolleary ?

Any ideas?

After further investigation, it appears that if `credentialSecret` is set to anything (`false` or your own choice of secret) then it works (and doesn't try to store a credentials document in the database). It's only if you let NR choose the default that you get the error.

@knolleary any idea whether is likely to be an error in my code or a bug somewhere in the core?

You are looking at the api layer between the internal storage system and the main runtime. There is not a one-to-one mapping between the internal api and the Storage Plugin API.

Internally, the runtime calls `getFlows` of the storage layer and that is expected to return both flows and credential objects. Internally, the storage layer calls the Storage Plugin's `getFlows` and `getCredentials` to assemble the proper response. See [node-red/packages/node\_modules/@node-red/runtime/lib/storage/index.js at master · node-red/node-red · GitHub](https://github.com/node-red/node-red/blob/master/packages/node_modules/@node-red/runtime/lib/storage/index.js#L75) for details.

Could you share the details of the syntax error?

If you were updating [node-red-app/cloudantStorage.js at master · IBM/node-red-app · GitHub](https://github.com/IBM/node-red-app/blob/master/cloudantStorage.js) to use the new SDK library under the covers, I don't see why you'd get different behaviours in the Node-RED \<--\> plugin interaction.
