Error 3:  

When we deploy the sharepoint assets with SPFx solution, we create elements.xml and schema.xml and  if the the format of both the file is not correct we will get the error mentioned below:

Invalid SharePoint App package. Error: Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it. 

Solution:

2 Build the solution and create the package.

3 Deploy it again.

Error 4: 

There were errors when validating the App manifest.: Xml Validation Exception: 'The 'Name' attribute is invalid - The value '-client-side-solution' is invalid according to its datatype
