Cannot read properties of null (reading 'map')

[illunix]

I use v1.13.0 Can someone help me resolve this, somehow Kiota can't handle null values

[andrueastman]

Thanks for raising this @illunix

Any chance you can share the path being called as well as the openApi description for the path? Are you able to determine which property is null that was expected to be a collection?

[illunix]

Everything in my response is expected, I will provide you open api description later

Hi @illunix Thanks for the additional information. This is caused by a lack of defensive check here. https://github.com/microsoft/kiota-typescript/blob/8c76a375bfab29d66e7ebe186f71342a1a2a4f54/packages/serialization/json/src/jsonParseNode.ts#L53

Would you be willing to submit a pull request to address this issue?

[illunix]

You mean it's missing something like @baywet

if (typeOfX === "null") {

}

[baywet]

more something like

if(!Array.isArray(this._jsonNode)) return undefined;

[SrRickGrimes]

same issue here. I am getting this exception:

TypeError: Cannot read properties of null (reading 'map') at JsonParseNode.getCollectionOfPrimitiveValues
