Using Odata conditional operator in query parameter gets error

Question

I'm doing test with Graph explorer. When I use following, everything works fine

1. https://graph.microsoft.com/v1.0/me/drive/root/children?$filter=startsWith(name, 'cdfs')
2. https://graph.microsoft.com/v1.0/me/drive/root/children?$filter=folder ne null

However, when I add conditional operator to between the two syntaxes, graph returns error:

https://graph.microsoft.com/v1.0/me/drive/root/children?$filter=folder ne null and startsWith(name, 'cdfs')

Does anyone encounter the problem? Or any help?

Thanks.

The returned error codes:

"code": "notSupported",
"message": "Operation not supported",

Even though your filter query format is correct with 'and' operator, as the error response indicates that Graph API filter does not support this.

However, this doesn’t mean that similar format API queries won’t work in other scenarios.

It’s just that in this particular case, it doesn’t function as expected due to the limitations of the Graph API filter.
