Getting issue while using model

[Dimple-Kanwar]

Hi,
I am getting `Error:

{ "index" : 0 }

` message from frontend but when I run the same function from cli, it is working fine.

sample Code:
Model.ts

 @nearBindgen
 export class Test 

 { id: i32; borrowAmount: i64; updatedAt: u128; borrower: string; lender: string; isEntity: bool; } 

part of function in Main.ts

 let tests = new PersistentMap<i32, Test>("t:");

let test: Test = 

 { id, borrowAmount, updatedAt, borrower,lender: Context.sender isEntity: true } 

logging.log(test); // error line

tests.set(id, test);

I tried converting this model into a proper class format with constructor but it's still giving me same error.

Do you have a link to the repo in question? Is this error in the log on the front end or is the whole call return this error?

[Dimple-Kanwar]

this exception is getting thrown from this call to frontend.

@Dimple-Kanwar I still don't have enough context, for example, what is the method that is exported? Do you have any other source code you could share?
