Could not resolve repository metadata error - 500 for profile endpoints

This issue is similar to https://github.com/spring-projects/spring-data-rest/issues/1729 .

Our app works as expected most of the time but occasionally we get a 404 error for some of our API endpoints.
When we check the /profile endpoint for that repository, it returns 500 with "Could not resolve repository metadata"
It works after a restart but then fails again after a while.

We use Spring-boot-starter-data-rest : 2.2.6.RELEASE

Example UseCase :

3 Entities :

1. Customer
2. AppTwitter
3. CustomerTwitter

A Customer can have multiple twitter Accounts (CustomerTwitter). One Twitter App( AppTwitter) can be used to handle multiple Customers

All of these entities have been exposed as repositories

Entites:

Customer.java

@Entity
public class Customer implements Serializable {

   private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @Column( unique = true)
    @NotBlank
    private String name;

    @ManyToOne
    @JoinColumn(foreignKey=@ForeignKey(name = "FK_CustomerToAppTwitter"),name="appTwitter_id",referencedColumnName = "twitterAppId")
    private AppTwitter appTwitter;

    @OneToMany(cascade = CascadeType.ALL,mappedBy = "customer")
    private List<CustomerTwitter> customerTwitter;

   // Getters and Setters here
}

AppTwitter.java

@Entity
public class AppTwitter implements Serializable {

   private static final long serialVersionUID = 1L;

    @Id
    private Integer twitterAppId;
    
    // Other fields specific to App

    @OneToMany(mappedBy = "appTwitter")
    private List<Customer> customer;
    
    //Getter and Setter
}

CustomerTwitter.java

@Entity
public class CustomerTwitter implements Serializable {

   private static final long serialVersionUID = 1L;

   @Id
   private String twitterId
   
   // Other fields related to twitter account

  @ManyToOne(fetch = FetchType.EAGER)
  @JoinColumn(foreignKey=@ForeignKey(name = "FK_CustomerTwitterToCustomer"), name="cust_id",referencedColumnName = "id")
  private Customer customer;
  
  // Getters and Setters
}

Repositories

CustomerRepository.java

@RepositoryRestResource
public interface CustomerRepository extends JpaRepository<Customer, Integer>{
    
}

AppTwitterRepository.java

@RepositoryRestResource
public interface AppTwitterRepository extends JpaRepository<AppTwitter, Integer>{
}

CustomerTwitterRepository.java

@RepositoryRestResource
public interface CustomerTwitterRepository extends JpaRepository<CustomerTwitter, String>{
}

Sometimes making a GET call to any one of these endpoints returns 404 error and the /profile endpoint gives 500 error with Could not resolve repository metadata

Weird thing is this happens once every 6-7 hours and almost never happens in my local environment to even figure out and debug the issue.
