Trouble upgrading from 12.1 to 13.0

[SamTS]

Hello,
Unsure if this is the right place for this, but I'm upgrading a project from kad-dht 12.1 to 13.0 and it isn't working for me.

I use this.libp2p.contentRouting.provide(new CID(multihash), (err) => { to provide a given multi-hash,
and then this.libp2p.contentRouting.findProviders(new CID(multihash), FIND_PROVIDER_TIMEOUT, (err, result) => { to find the content. It works in 12.1 and then fails in 13.0.

Because it might be important, here are my full dependencies "@nodeutils/defaults-deep": "^1.1.0", "async": "^2.6.1", "bluebird": "^3.5.1", "body-parser": "^1.18.3", "bs58": "^4.0.1", "chai": "^4.2.0", "cids": "^0.5.3", "commander": "^2.17.1", "debug": "^3.1.0", "express": "^4.16.4", "js-yaml": "^3.12.1", "libp2p": "^0.24.0", "libp2p-kad-dht": "^0.12.0", "libp2p-mdns": "^0.12.0", "libp2p-mplex": "^0.8.0", "libp2p-railing": "^0.9.2", "libp2p-secio": "^0.11.0", "libp2p-tcp": "^0.13.0", "mocha": "^5.2.0", "multihashing-async": "^0.5.1", "node-cmd": "^3.0.0", "node-forge": "^0.7.6", "peer-book": "^0.7.0", "peer-info": "^0.14.1", "pull-stream": "^3.6.8"

Any suggustions or a point in the right direction would be much appreciated!
