Is it possible to add values to GetFieldDeserializers?

[pennan88]

I have a customer who uses a CRM system and has created a schema that I used in Kiota to generate all the models. However, the customer made some mistakes with the date fields—some are labeled as $date-time, while others are just $date. As a result, some fields are generated as Date?, while others become DateTimeOffset?. They should all be DateTimeOffset?

Ideally, they would fix their documentation, but that would likely take a long time. I’d rather not modify the schema myself in case we need to regenerate it later.

I tried extending the existing model with my own property, but that didn’t work.

public partial class Application
{

    [JsonPropertyName("startdate")]
    public DateTimeOffset? StartDate { get; set; }
    
}

Is it possible to extend or override the GetFieldDeserializers?

Hi @pennan88
Thank you for using kiota and for reaching out.

No, it's not possible.

For those scenarios we recommend that people use overlays to apply patches to an existing specification they don't own. Use third party tooling to generate the patched specification, and then feed that to kiota.

The overlay itself can be committed to the repository.

Let us know if you have any additional comments or questions.

Hi!
Thanks for the response. I'll check overlays out
