Simple file based key value store (GetKey)

Read a value by key from a local json file. Related workflow: WriteKey Create a subfolder in your n8n homedir: /home/node/.n8n/local-files. In docker look at the data path and create a subfolder local-files. Set the correct access rights chmod 1000.1000 local-files. Put the workflow code in a new workflow named GetKey. Create another workflow with a function item: return { file: '/4711.json', // 4711 should be your workflow id key: 'MyKey', default: 'Optional returned value if key is empty / not exists' } Pipe the function item to an Execution Workflow that calls the GetKey workflow. It would be nice if we could get someday a shiny built-in n8n node that does the job. :)

Help me set up the n8n workflow "Simple file based key value store (GetKey)" (https://n8n.io/workflows/1408). It uses: . Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
