I'm working on an IoT project that involves storing data in a database.
Hi everyone,
I'm working on an IoT project that involves storing data in a database. While writing the SQL code, I encountered the following error:
"violated - parent key not found"
I search everywhere, Has anyone else encountered this issue, or can anyone provide guidance on how to fix

Thank you @jjbitnic
