Looking for some help with ganache usage via node.js:

I am testing a bridge application which tries to spawn multiple ganache-server instances for setup. I have the following function which was working fairly well on ganache-cli: "^6.12.2":

import ganache from 'ganache-cli';

export type GanacheAccounts = {
  balance: string;
  secretKey: string;
};

export function startGanacheServer(
  port: number,
  networkId: number,
  populatedAccounts: GanacheAccounts[],
  options: any = {}
) {
  const ganacheServer = ganache.server({
    accounts: populatedAccounts,
    port: port,
    network_id: networkId,
    _chainId: networkId,
    chainId: networkId,
    _chainIdRpc: networkId,
    ...options,
  });

  ganacheServer.listen(port);
  console.log(`Ganache Started on http://127.0.0.1:${port} ..`);

  return ganacheServer;
}

I am testing another process in parallel - a relayer - which listens to events on one ganache instance and issues transactions on the other ganache instances. I am trying to debug some functionality on the relayer and I believe the instamine feature of ganache could be having an effect.

My problem is that I attempt to change the above code to include a blockTime: 2, entry into the options of the server() call. And now in test setup I see errors such as Error: the tx doesn't have the correct nonce. account has nonce of: 15 tx has nonce of: 14.

I am in the process of attempting similar changes but bumping the version to "ganache": "^7.0.0-beta.2". I would appreciate any ideas on what could be the cause of the above error! Thank you.
