Extend Item Entity API problem with itemattributes jsonarray

Posted on by Community Member Microsoft Employee

Hello!

I am trying to extend the default "Item Entity" API Page in NAV BC. What I want is to add a jsonarray to a new property on the page called "ItemAttributes"

Problem is when I run this API in Postman the value of the property "ItemAttributes" is returned as a string and not as an jsonarray.

Hello

I dont think this is supported in extensions. At least not in target='Extension' in app.json

I tried to subscribe to 'ApiSetup' in CU Graph Mgt - General Tools in order to inject a custom EDM type but I get this error

The type or method 'InsertOrUpdateODataType' cannot be used for 'Extension' development

You’re right, missed the “.

I think it’s because your itemAttributes field is a text field. You should do like the baseUnitOfMeasure field, so in the API Page a field with a tablerelation. Check how that field is managed.

I dont think so.

The problem is the trailing slashes \ and the quote

A valid array would be

{

"itemAttributes": [{................. }]

}

but in my case I get

{

"itemAttributes": "[{.....................}]"

}

It seems correct to me, this is an array of objects:

[

{

"Height":60,

"Width":100,

"Lenght":55

}

]
