ERROR: Cannot read properties of undefined (reading 'map')

[test123-all]

Hey, I happily found your influxdb node for n8n. But I can't get the block to work. Since there is no documentation, am I doing something wrong?

I get the following error:

ERROR: Cannot read properties of undefined (reading 'map')

Stack
TypeError: Cannot read properties of undefined (reading 'map')
    at Object.execute (/home/node/.n8n/nodes/node_modules/n8n-nodes-influxdb/nodes/InfluxDb/InfluxDb.node.ts:50:78)
    at Workflow.runNode (/usr/local/lib/node_modules/n8n/node_modules/n8n-workflow/dist/Workflow.js:659:28)
    at /usr/local/lib/node_modules/n8n/node_modules/n8n-core/dist/WorkflowExecute.js:585:53

I tried the following:

• converting the parameters to arrays
• putting '"' signs around the names
• putting ',' behind each representation
• using a different user token for the authentication

The code/JSON to reproduce my not working minimal example n8n block workflow is:

I just had the same problem and the solution for me was adding a default tag and supplying any value.
