I get Error 0x80070057 when I use the CfCreatePlaceholder function from the Cloud Filter API

Question

I am using a Windows 10 laptop.
i am using the Cloud Filter API and I want to create a placeholder in the sync root directory.
This is how I initialised the place_holder table:
// SyncRoot is already created
SyncRoot.c_str = "C:\client"
FilePath.c_str() = "file.bin"
CF_PLACEHOLDER_CREATE_INFO place_holders[1];
place_holders[0].RelativeFileName = FilePath.c_str();
place_holders[0].FsMetadata.BasicInfo.FileAttributes = FILE_ATTRIBUTE_NORMAL;
place_holders[0].FsMetadata.FileSize.QuadPart = 1024 * 1024 * 1024;
place_holders[0].Flags = CF_PLACEHOLDER_CREATE_FLAG_SUPERSEDE | CF_PLACEHOLDER_CREATE_FLAG_MARK_IN_SYNC;
place_holders[0].FileIdentity = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, 0x130);
place_holders[0].FileIdentityLength = 0x130;
DWORD processed;
res = CfCreatePlaceholders(SyncRoot.c_str(), place_holders, 1, CF_CREATE_FLAG_NONE, &processed);
But it returns an error 0x80070057.

Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query.

Windows encountered a storage problem, as indicated by the 0x80070057 error code. It's possible that there wasn't enough room on your hard disk or SSD to download or copy files. However, this error could also be an indication of a hard drive corruption, an incompatible file system, or any other storage-related problem.

A missing update may be the reason why error code 0x80070057 appeared if Windows Update was not the source. Press Win + I, then do the following to see whether you have any pending updates:

From the Settings app, select the Windows Update option, then click Check for updates.
