Sending array to API and getting empty list

Question

I wrote a function in angularjs, that send the array to API. (I'm using asp.net).

function getDimensionTagsByIds(tagIds) {

        return msApi.resolve('app.entities.dimensions-tags-search@query', {tagsId: tagIds});
    }

this is the function in the API that receives this request:

[HttpGet]
    [Route("tags-search")]
    [EnableQuery]
    public async Task<IQueryable<SimpleDimensionViewModel>> SearchTags([FromUri] List<int> tagIds)
    {
        return (await _mediator.SendAsync(new ProjectedQuery<DimensionTag, SimpleDimensionViewModel>())).Where(dt => tagIds.Contains((int)dt.TagId));
    }

when I debug my code I see that the tagIds get all the time empty List. I tried to change the parameter to array, but its still doesn't work. what I'm doing wrong?

thanks for the help!

You are sending object with "tagsId" property. Plural tagS and singular Id. And your parameter is singular - tag and plural IdS — JleruOHeP

no, tagsid is an array of string, I tried to change the type of the list to be list<string> but it still, refuse to work — Elior Sastiel

Sorry, maybe I was not clear - I meant that you have different names there. tagsid vs tagids. If you have different types on top of it - the app should throw the conversion exception. To debug it you could change the list to have strings instead of ints - just for testing — JleruOHeP

You have a simple typo:

Your angular is sending property tagsId And your backend is waiting for tagIds
