Hi there !

I am working on my OWB project.  
It is very similar to NBA TopShot, just more decentralized. The idea is that celebrities could put their digital assets into decks and then people could mint those assets and sell them.

So I took a lot of inspiration from the NBA smart contract and tried to make it possible for anyone to be an admin of his own ecosystem.  
Given that when reading the code you can think deck = set in NBA TopShot, memento = Play in NBA TopShot

**Problem :**  
When submitting the transaction2 (to create a deck and put it in the admin resource) I get an error from the emulator : **fatal error : stack overflow**

\*\*Code : \*\*

From the stack trace it looks like there’s a Cadence value that is converted to a string, but it references itself, so there’s an infinite loop.

I opened [a bug report in the Cadence repo](https://github.com/onflow/cadence/issues/349) to track this.

From what I can see, this is likely caused by these fields storing with reference types (there might be more):

- [https://github.com/Robin-Bonnin/Toke/blob/062ac694625692e8163824f0218e0241a6ac0821/acct\_3\_Toke.cdc#L40](https://github.com/Robin-Bonnin/Toke/blob/062ac694625692e8163824f0218e0241a6ac0821/acct_3_Toke.cdc#L40)
- [https://github.com/Robin-Bonnin/Toke/blob/062ac694625692e8163824f0218e0241a6ac0821/acct\_3\_Toke.cdc#L91](https://github.com/Robin-Bonnin/Toke/blob/062ac694625692e8163824f0218e0241a6ac0821/acct_3_Toke.cdc#L91)

In the latest version of Cadence fields with a reference type are not valid anymore, references cannot be stored, they are short-lived and only exist during the life-time.

Instead of using a reference, consider replacing it with a capability, i.e., instead of using `&Admin`, use `Capability<&Admin>`, and where you use the field, `borrow` the capability to get the reference.

I still need to investigate why executing the transaction results in the string conversion.
