Why is my local DropBox folder not readable with java?

It turns out that all of the individual files in the folder do not have ANY permissions for users other than me. As such the folder itself is not readable.

I am running the java app to read the directory and files from my IntelliJ IDE. I am not sure who the user is when the IDE runs.

But I am not sure why the permissions are so narrow. The folder is populated programmatically with files from a java app running in Google Cloud.

What controls the file permissions?

Here are code excerpts:

DbxClientV2 client = getDbxClientV2( );

try ( InputStream in = new ByteArrayInputStream( fileBytes ) ) {

FileMetadata metadata
= client.files( )
.uploadBuilder( filePath )
.uploadAndFinish( in );

///…

}

public DbxClientV2 getDbxClientV2( ) {

String accessToken = this.getAccessToken( );

DbxRequestConfig config
= DbxRequestConfig
.newBuilder( this.getAppIdentifier( ) )
.build( );

DbxClientV2 client = new DbxClientV2( config, accessToken );

return client;

}
