Topic: Error with Data Fetch - Invalid array length

The express generator has a Darwinx.json. The json only has currencies and commodities. How do I upgrade it to add the crypto for Darwinx-Live as they have ADAUSD, BNBUSD, BTCUSD, DOGEUSD, ETHUSD, SOLUSD, XRPUSD. I tried adding them nanually inside the darwinx.json but when I run download data I get this error

C:\express-generator>node  ./bin/fetch.js  --fx-rates true  --symbols ADAUSD BNBUSD BTCUSD DOGEUSD ETHUSD SQLUSD XLMUSD XRPUSD   --periods M1 M5 M15 M30 H1 H4 D1  --max-bars 200000  --time-zone 0

Re: Error with Data Fetch - Invalid array length

Hello Tobeawinner,

Thank you for your report.

I tested the exact command, and it works fine. It must be a network or other temporary issue.

Please note that Express Generator can fetch only the symbols we provide.

See my screenshot:

If you continue to experience this issue, please report it again. I'll take a deeper look.
