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. 🙋
I am trying to but I get that error 400 - it's asking for template_id. What template is it referring to?

toki4004 The 'property_groups' parameter on the /2/files/upload endpoint is optional. (You can find that in the documentation for /2/files/upload.) You should only set it if you are using the "file properties" feature. If you do set the 'property_groups' parameter though, the 'template_id' field in any given PropertyGroup object is required and must not be empty.
You can find information on the file properties feature, such as what templates are and how to work with them, in the documentation for it here.
