ReferenceManyField uncaught at handleFetch TypeError: payload.data.map is not a function

[l0ne]

Hello! I try to implement datagrid in tabbed form.

What you were expecting: Request to api looks good: http://localhost:3001/api/v1/projectRounds?_end=25&_order=DESC&_sort=id&_start=0&projectId=505

What happened instead: If I try response: [{"id":13,"projectId":505,"createdAt":"2017-11-17T00:24:34.000Z"}]

In console I have error: Uncaught TypeError: Cannot read property 'data' of undefined at oneToMany.js:47

try response: {"data":[{"id":13,"projectId":505,"createdAt":"2017-11-17T00:24:34.000Z"}],"total":1}

Having: uncaught at handleFetch TypeError: payload.data.map is not a function at ./node_modules/admin-on-rest/lib/reducer/admin/references/oneToMany.js.exports.default (http://localhost:3000/static/js/bundle.js:16316:125)

...
<FormTab label="Project rounds">
    <ReferenceManyField reference="projectRounds" target="projectId" addLabel={false}>
        <Datagrid>
            <TextField source="id" />
        </Datagrid>
     </ReferenceManyField>
</FormTab>
...

Hi, and thanks for your question. As explained in the admin-on-rest contributing guide, the right place to ask a "How To" question, get usage advice, or troubleshoot your own code, is StackOverFlow.

So I'm closing this issue, and inviting you to ask your question at:

Hi, thanks for answer!

I think it's not "How To" question becouse I faced with error from you library. I used you admin-on-rest demo and documentation for try it. Request to json file in you demo working correct, but not correct working GET_MANY_REFERENCE with response from rest api. Crashing application when response processing.

Also, if the data in the response is not the same like need you component, can you add a  conditions for check without crashing the application?

Thank you very much!

I consider it's a not bug because it works on the demo:

https://github.com/marmelab/admin-on-rest-demo/blob/a67978a6f69e7dfbb937f66baaa49e787e5853ec/src/visitors/index.js#L82-L93

Therefore I believe there is an error in your restClient. I advise to ask for help in stackOverflow for properly configuring it.
