The specified module was not found

[KaiserEngi]

I was able to install the saprfc module successfully. Unfortunately, this error message always appears when starting Node-Red. Do you have any idea what it could be?

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials file will not be recoverable, you will have to delete it and re-enter your credentials.

You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

It seems the node-red-contrib-saprfc cannot find the node-rfc module. Do you have a fully functional node-rfc installation?

[KaiserEngi]

I'm beginning to understand the connections. No, the installation of node-rfc fails with the following message:

The installation worked. The following update was still missing for the SDK to work properly:

Unfortunately I am now missing the config node. Do you have any idea what the problem could be? Everything else works without any problems.

[PaulWieland]

Node RED config nodes are inside the properties panel of the regular nodes.. Drag a read table node in and double click it, then add your sap connection info.

[KaiserEngi]

Ah very good, I've found it.

Many thanks for your help
