Invalid Include Path Error in Asp.net 6 Web API - api

Question

After Adding a Include property on the parent model controller I am facing the following error:
'Microsoft.EntityFrameworkCore.Query.InvalidIncludePathError': Unable to find navigation ' CurrencyList' specified in string based include path ' CurrencyList'. This exception can be suppressed or logged by passing event ID 'CoreEventId.InvalidIncludePathError' to the 'ConfigureWarnings' method in 'DbContext.OnConfiguring' or 'AddDbContext'.'
I am sharing all the related class & model.
CurrencyList (Model) : This is the child class which I want to include into the parent class for populating the dropdown.
public class CurrencyList
{
[Key]
public int Id { get; set; }
[DisplayName("CURRENCY")]
[Required(ErrorMessage = "CURRENCY is a required field")]
public string? CurrencyName { get; set; }
[DisplayName("EXCHANGE RATE")]
[Required(ErrorMessage = "EXCHANGE RATE is a required field")]
public double Rate { get; set; }
}
CurrencyList Controller:
public class CurrencyListController : ControllerBase
{
private readonly IUnitOfWork _unitOfWork;
public CurrencyListController(IUnitOfWork unitOfWork)
{
_unitOfWork = unitOfWork;
}
[HttpGet]
public IEnumerable<CurrencyList> Get()
{
IEnumerable<CurrencyList> objCurrencyDropDownList = _unitOfWork.Currency.GetAll();
return _unitOfWork.Currency.GetAll();
}
[HttpGet("{id:int}")]
public CurrencyList GetDetails(int id)
{
return _unitOfWork.Currency.GetDetails(id);
}
[HttpPost]
[ProducesResponseType(StatusCodes.Status201Created)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
public IActionResult Create(CurrencyList obj)
{
if (ModelState.IsValid)
{
_unitOfWork.Currency.Add(obj);
_unitOfWork.Save();
return CreatedAtAction("GetDetails", new { id = obj.Id }, obj);
}
return BadRequest();
}
[HttpPut]
[ProducesResponseType(StatusCodes.Status204NoContent)]
[ProducesResponseType(StatusCodes.Status400BadRequest)]
public IActionResult Edit(CurrencyList obj)
{
if (ModelState.IsValid)
{
_unitOfWork.Currency.Update(obj);
_unitOfWork.Save();
return NoContent();
}
return BadRequest();
}
[HttpDelete]
[ProducesResponseType(StatusCodes.Status204NoContent)]
[ProducesResponseType(StatusCodes.Status404NotFound)]
public IActionResult Delete(int? id)
{
var obj = _unitOfWork.Currency.GetFirstOrDefault(c => c.Id == id);
if (obj == null)
{
return NotFound();
}
_unitOfWork.Currency.Remove(obj);
_unitOfWork.Save();
return NoContent();
}
}
BTBNewLienOpening (Model) : This is the parent class where I created FK retalion with CurrencyList Model.
public class BTBNewLienOpening
{
[Key]
public int ExpLCNoId { get; set; }
[DisplayName("EXPORT L/C NO")]
[ValidateNever]
public string? ExpLCNo { get; set; }
[DisplayName("ORDER NO")]
[ValidateNever]
public string? OrderNo { get; set; }
[DisplayName("STYLE")]
public int? StyleListId { get; set; }
[ForeignKey("StyleListId")]
[ValidateNever]
public StyleList? StyleList { get; set; }
[DisplayName("VALUE")]
[ValidateNever]
[DisplayFormat(DataFormatString = "{0:C}", ApplyFormatInEditMode = false)]
public decimal? Value { get; set; }
[DisplayName("NET VALUE")]
[ValidateNever]
[DisplayFormat(DataFormatString = "{0:C}", ApplyFormatInEditMode = false)]
public decimal? NetValue { get; set; }
[DisplayName("CURRENCY")]
public int? CurrencyListId { get; set; }
[ForeignKey("CurrencyListId")]
[ValidateNever]
public CurrencyList? CurrencyList { get; set; }
[DisplayName("QTY PCS")]
[ValidateNever]
public string? QtyPcs { get; set; }
[DisplayName("SHIPMENT")]
[ValidateNever]
public string? Shipment { get; set; }
[DisplayName("EXPIRY DATE")]
[ValidateNever]
public string? Expiry { get; set; }
[DisplayName("COUNTRY")]
public int? CountryListId { get; set; }
[ForeignKey("CountryListId")]
[ValidateNever]
public CountryList? CountryList { get; set; }
}
BTBNewLienOpeningController : This is the controller where I use the include properties for including all the dropdown properties. In the GetAll() method I use the include properties and include the dropdown properties. If I run the program without CurrencyList the app works fine. But after adding CurrencyList it shows the Microsoft.EntityFrameworkCore.Query.InvalidIncludePathError'
public class BTBNewLienOpeningController : ControllerBase
{
private readonly IUnitOfWork _unitOfWork;
private readonly ILogger<BTBNewLienOpeningController> _logger;

_unitOfWork = unitOfWork;
_logger = logger;

Repository (Class) : Here I use the GetAll method and added the include functionality.
public class Repository<T> : IRepository<T> where T : class
{
private readonly ApplicationDbContext _db;
internal DbSet<T> dbSet;
public Repository(ApplicationDbContext db)
{
_db = db;
this.dbSet = _db.Set<T>();
}
public void Add(T entity)
{
dbSet.Add(entity);
}
public IEnumerable<T> GetAll(string? includeProperties = null)
{
IQueryable<T> query = dbSet;
if (includeProperties != null)
{
foreach (var includeProp in includeProperties.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProp);
}
}
return query.ToList();
}
public T GetFirstOrDefault(Expression<Func<T, bool>> filter, string? includeProperties = null)
{
IQueryable<T> query = dbSet;
query = query.Where(filter);
if (includeProperties != null)
{
foreach (var includeProp in includeProperties.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProp);
}
}
return query.FirstOrDefault();
}
public T GetDetails(int id)
{
return dbSet.Find(id);
}
public void Remove(T entity)
{
dbSet.Remove(entity);
}
public void RemoveRange(IEnumerable<T> entity)
{
dbSet.RemoveRange(entity);
}
public IEnumerable<T> GetProp(string? includeProperties = null)
{
IQueryable<T> query = dbSet;
if (includeProperties != null)
{
foreach (var includeProp in includeProperties.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries))
{
query = query.Include(includeProp);
}
}
return query.ToList();
}
