Query components this/metadata

HEllo,

I have a CDE dashboard that is running wihtuot any issue on pentaho 5.4 CE.

I tried to migration it to pentaho 7.0, but "Query component" is not working properly anymore.

In the component in Post Execution I use
this.metadata
this.queryInfo
this.resultset
However these are now undefined.

So, what is now the correct way to get details of my query?

Do not hesitate if you need more details.

Thanks by advance for your help.
Brgds
