I'm not sure if this is a bug.

What happened?

When I use parameter to insert vertex, nebula show me an error: -1005:Storage Error: The data type does not meet the requirements. Use the correct type of data.

About my env

• OS: CentOS
• Deploy Style: single-machine
• Installation Style: Docker
• Nebula Version: 3.1.0
• Prod-env: N

How To Reproduce

Steps to reproduce the behavior:

0. Tag of vertex

1. Set the parameter in Nebula Studio

   :param name=> 'Test';

   Success

2. Test the parameter

   return $name

   Output: Test

3. Insert vertex with parameters

   INSERT VERTEX `person` (
       `name`  
   )
   VALUES "RandowId": (
       $name
   )

   -1005:Storage Error: The data type does not meet the requirements. Use the correct type of data.

Others

When I invoke the method (com.vesoft.nebula.client.graph.net.Session#executeWithParameter), if the parameter is a vertex prop, the error happend too.
Reference other repo of nebula using in java, they use com.vesoft.nebula.client.graph.net.Session#execute to doing their work. For example nebula-jdbc and etc. Maybe it's this problem that stops them. By the way, when we use string splicing to assemble stmt, it may cause a danger that supports nGQL injection I guess.

Thanks, this is the requirements on parameter support on dml.
