I’m trying to pass multiple nids to my node to match this structure:

[field_sac_testts] => Array             (                 [x-default] => Array                     (                         [0] => Array                             (                                 [target_id] => 168                             )                          [1] => Array                             (                                 [target_id] => 175                             )                      )              ) 

I’ve tried this:

{“_links”:{“type”: {“href”:”http://mywebsite.com/rest/type/node/subject”}},”type”:[{“target_id”:”subject”}],”field_sac_testts”:[{“0”: {“target_id”:”702}},{“1”: {“target_id”:”729″}}]}

And a bunch of other combinations and I can’t seem to get it to PATCH successfully. I keep getting a syntax error.

If anyone could help that would be great. Thanks.
