Getting error when opening an existing project and on new project

Getting error while opening as existing project .Please help me on these.

Hey Madhuri,

check whether any un assigned variable is there
This error always occurs when you have an array or table or other variable with no data.

Hi @Madhuri1,

Try to close and restart everything, if it does not work

In your project folder delete json file and run

Thanks,
