Can't retrieve data

[matteoberla]

Hi,
I've set up both aggr and aggr-server locally (no docker, just on my localhost)

-Is it possible to run it without influxDb? (I see that ./data dir is populated with exchanges pairs data)

When I open aggr on http://localhost:8081/ I see an error on the terminal where I've started aggr-server.
Every time I try to refresh the page this is printed on the terminal:

TypeError: Cannot read properties of undefined (reading 'format')

What am I doing wrong? Am I missing something?

aggr-server:
-I've copied the config.json.example into config.json without any changes
-I've tries to comment INFLUX_HOST and INFLUX_PORT from .env file

http://localhost:3000/ responds with {"message":"hi"} so I think it's set up correctly

aggr:
-I've added API_URL with the url of the server (http://localhost:3000/) to .env and .env.production, also tried to run with API_URL=http://localhost:3000/ npm run serve

Aggr without the historical data works fine (even if I see some errors on the webpage)
When I try to add the aggr-server connection nothing changes except for the error I see in the terminal

While aggr-server is designed to save tick data in /data (as file), the client cannot make use of it directly as a source for populating the chart in realtime, its way to much data. Influx will take care of it for compressing the raw data into timeframes. Trade files in /data is used as a backup for influx or other external charting / analysis purposes

So I need to setup influx in order to see all the historical data in the chart, right?
