Feature Description

I want to return actionable error messages to clients when an error occurs. In the case of an EntityNotFoundError being throw, I want to provide a formatted error with the entity type and a variation of the query/criteria.

The Solution

Expose the data passed to the EntityNotFoundError constructor.

export class EntityNotFoundError extends TypeORMError {
    public readonly entityClass: EntityTarget<any>;
    public readonly criteria: any;

    constructor(entityClass: EntityTarget<any>, criteria: any) {
        super();

        this.entityClass = entityClass;
        this.criteria = criteria;

        this.message =
            `Could not find any entity of type "${this.stringifyTarget(
                entityClass,
            )}" ` + `matching: ${this.stringifyCriteria(criteria)}`
    }
    ...
}

Considered Alternatives

Parsing the message is brittle, and not ideal.
