resolves #790

Added an artificial delay to createManyCallback() to validate:

Screen.Recording.2024-11-22.at.11.23.33.AM.mov

Code w/ Delay (replace `createManyCallback()` with the below)

``` export const createManyCallback = ( document: ModelTypes, metadata: ModelMetadata, extra: any, options: saveOptions = {}, ): Promise => { const Model = metadata.ottoman.getModel(metadata.modelName);

// Function to introduce a delay
const delay = (ms: number) => new Promise((resolve) => setTimeout(resolve, ms));

// Artificial delay before calling Model.create
const artificialDelay = 2000; // Delay in milliseconds (e.g., 1000ms = 1 second)

return delay(artificialDelay)
.then(() => Model.create(document, options))
.then((created) => {
console.log(Successfully wrote document at ${new Date().toISOString()});
return Promise.resolve(new StatusExecution(created, 'SUCCESS'));
})
.catch((error) => {
/* istanbul ignore next */
return Promise.reject(new StatusExecution(document, 'FAILURE', error.constructor.name, error.message));
});
};
