how to return nested data from joined tables from update query

Note: using `/v1/query` and know its deprecated, we want to update to the regular graphql endpoint at some point, but we’re stuck with some legacy code for now

i want my update query to return nested data from joined tables like

```
"returning":[
"id",
"name",
{
"name":"sometable",
"columns":[
"*"
]
}]
```

the object style is working for get one and get many queries, but not for create or update queries.

I get this error: `"parsing Text failed, expected String, but encountered Object"`

is this even possible? would it work if we updated to v2?

Start by comparing the deprecated /v1/query endpoint with the regular GraphQL endpoint and its v2 behavior. Trace how the returning value is handled for update queries, especially the nested object for joined tables. Done means establishing whether nested returning data is supported and documenting the applicable endpoint or limitation.
