Trying to sync node but Mongo collections still empty.

[danesposi]

I'm running my own bitcoin node on my local machine, already built bitcore, started a MongoDB container with the correct port mapping and connected bitcore to my local node via bitcore.config.json.

The logs don't seem to show any error, but after a long time of syncing I try to query the MongoDB collections and get an empty array. Also, I get no data from any block.

MongoDB version: 8.0.8.
Node version: 23.11.0.

The only syncing logs I get:

info :: 2025-04-16T17:30:51.124Z :: This worker is now the syncing node for BTC mainnet
info :: 2025-04-16T17:30:51.161Z :: 2025-04-16 12:30:51.161 GMT-5 | Syncing 2000 blocks | Chain: BTC | Network: mainnet

I also get the following warning:

(node:19058) [MONGODB DRIVER] Warning: Current Server Discovery and Monitoring engine is deprecated, and will be removed in a future version.

I greatly appreciate any help.

Thanks in advance.

I got the same issue

The warning is happening because bitcore uses an old configuration for Node.js Mongo driver. we need to include useUnifiedTopology option in the Mongo client. I have done this but this introduces some additional errors which might take some time to fix.
