typeorm: Could not find any entity of type when using specific commands.

Issue Description

Queries work when I use either QueryBuilder or Raw SQL, using find, findOne, getOne etc returns nothing.

Expected Behavior

The any query created with the following would return the expected user:

await db.getRepository<User>('User').findOneOrFail({ emailAddress });

// return
User {
firstName 'Foo',
lastName: 'Bar',
emailAddress: 'foo@bar.com'
}

Actual Behavior

await db.getRepository<User>('User').findOneOrFail({ emailAddress });
// "Could not find any entity of type \"User\" matching: {\n    \"emailAddress\": \"foo@bar.com\"\n}"

await db.getRepository<User>('User').createQueryBuilder()
    .where('emailAddress = :emailAddress', { emailAddress: `${emailAddress}` })
    .getOne();
// returns undefined

await db.getRepository<User>('User').createQueryBuilder()
    .where('emailAddress = :emailAddress', { emailAddress: `${emailAddress}` })
    .execute();
// works

Steps to Reproduce

Code was working fine locally and deployed, before completing a new deployment. Upon completing a new deployment (none of the above code was changed), the error began appearing. The error transferred to my local environment when I performed a fresh node_modules install (It was not happening until that happened, regardless of the status of the deployed version).

1. Calling any find/findOne/getOne/findOneOrFail command reproduces the issue

@Entity('user')
export class User {
  @PrimaryGeneratedColumn()
  userId: number;

  @Column({ type: 'varchar', unique: true, length: 255 })
  emailAddress: string;

  @Column({ type: 'varchar', default: '' })
  phoneNumber: string;

  @Column({ type: 'varchar', default: '' })
  title: string;

  @Column('text')
  preferredName: string;

  @Column('text')
  firstName: string;

  @Column('text')
  lastName: string;

  @Column({ type: 'varchar', default: '' })
  profilePhotoURL: string;

  @Column('text')
  accountType: string;
}

export const getUserQuery = async (emailAddress: string) => {
  const db = await initDb(`${process.env.NODE_ENV}-db`); // Even hard-coding the selected DB makes no impact, have checked that.
  return db.getRepository(User).findOneOrFail({ emailAddress });
