Even when you have one property group it should be a list with one entry, not just a single string, as you have passed. If you take a look on 'filter_some', you will see that expected type is list, not something else (list of ids, not just one id itself - even when it's alone). Wrap your id' string with array.

Dropbox Stafftoki4004 As Здравко linked to, the API v2 Explorer is a good tool for prototyping and inspecting how API calls should be formatted.
I see in your code you're using json_encode on the property_groups value directly. The value is supposed to be a list, but note that json_encode itself returns a string, you're actually sending that parameter value as a string instead of the expected list. It looks like you could do so by removing that first json_encode call and just supplying the $meta variable itself.
Thanks, I am a newbie, wondering if you could help:
From the explorer page, I get this error
... "Dropbox-API-Arg": property_groups.template_id: '' must be at least 1 characters, got 0Is the template required? All I am trying to do is save a custom metadata snippet with the file.
I tried removing that first json_encode call and just supplying the $meta variable. Now I get the error:
"... property_groups: expected list, got builtins.dict"
toki4004, did you prototype your calls? As seems not yet... Yes, property group is list/array. The elements of this list are dicts. The fields of each element is list also.
Take a bit more care. 🙋
