'How to fix / debug errors (invalid arrayify value) when deploying a solidity contract in Remix

Problem

I am trying to deploy a smart contract via Remix. Unfortunately, it fails with a very unhelpful error message.

Error Message

creation of MyContract errored: Error encoding arguments: Error: invalid arrayify value (argument="value", value="", code=INVALID_ARGUMENT, version=bytes/5.5.0)

Code

Here is the constructor the contract uses:

struct RRSet {
    uint32 inception;
    uint32 expiration;
    bytes20 hash;
}

constructor(bytes memory _anchors) {
    // Insert the 'trust anchors' - the key hashes that start the chain
    // of trust for all other records.
    anchors = _anchors;
    rrsets[keccak256(hex"00")][DNSTYPE_DS] = RRSet({
        inception: uint32(0),
        expiration: uint32(3767581600), // May 22 2089 - the latest date we can encode as of writing this
        hash: bytes20(keccak256(anchors))
    });
    emit RRSetUpdated(hex"00", anchors);
}

Some thoughts

My contract uses is to inherit from an abstract contract as wells as from a regular contract. Is there a way to see where to error or originates from or is there a possiblity to debug it?
