How to use the @salesforce/command.core.SfdxError function in @salesforce/command

const conn = this.org.getConnection();
    const query = 'Select Name, TrialExpirationDate from Organization';

    // The type we are querying for
    interface Organization {
      Name: string;
      TrialExpirationDate: string;
    }

    // Query the org
    const result = await conn.query(query);

    // Organization will always return one result, but this is an example of throwing an error
    // The output and --json will automatically be handled for you.
    if (!result.records || result.records.length <= 0) {
      throw new core.SfdxError(messages.getMessage('errorNoOrgResults', [this.org.getOrgId()]));
    }

    // Organization always only returns one result
    const orgName = result.records[0].Name;
    const trialExpirationDate = result.records[0].TrialExpirationDate;

    let outputString = `Hello ${name}! This is org: ${orgName}`;
    if (trialExpirationDate) {
      const date = new Date(trialExpirationDate).toDateString();
      outputString = `${outputString} and I will be around until ${date}!`;
    }
    this.ux.log(outputString);

    // this.hubOrg is NOT guaranteed because supportsHubOrgUsername=true, as opposed to requiresHubOrgUsername.
    if (this.hubOrg) {
      const hubOrgId = this.hubOrg.getOrgId();
