Getting Error : The script reverted with reason Unknown

TypeScript SDK
1

I am getting “The script reverted with reason Unknown error” when trying to call the contract function. What can be the reason?

Following is the contract function I am trying to access

#[storage(read)]
fn get_item(item_id: u64) -> Item{
    return storage.lease_map.get(item_id).try_read().unwrap();
}

This is how my javascript looks like:

 async getItem(itemId: string) {
    if (this.contractO != null) {
      let value = await this.contractO.functions
        .get_item(itemId)
        .callParams({
          gasLimit: 1,
        })
        .txParams({
          gasPrice: 1,
          gasLimit: 100_000,
        }).call();
      console.log(value)
      return value
    } else {
      return null
    }
  }

Hi, thanks for reporting.

What version of the TS SDK / fuels are you using?

hi @anderson

Following are the versions

“@fuel-ts/wallet”: “^0.73.0”,
“@fuel-wallet/sdk”: “^0.16.1”,
“fuels”: “^0.76.2”,

I think you may have some version mismatch between your components.

Please try again by using fuels @ v0.73.0, and let me know how it goes.

{
  "fuels": "^0.73.0",
}

I tried with this but same error remaining

“@fuel-ts/wallet”: “0.73.0”,
“@fuel-wallet/sdk”: “0.15.2”,
“fuels”: “0.73.0”,

I sorted out this error. I tried lots of things but I guess it was fixed after I changing gasLimit to a higher number. (“fuels”: “0.73.0”,)

let value = await this.contractO.functions
.get_lease(leaseId)
.txParams({
gasPrice: 1,
gasLimit: 500_000,
}).call()

Finally, I realized the reason for this error is, failing one of the condition validations I had created on my contract. Wondering how to get the actual validation error

Thanks for letting me know. There are some ongoing efforts to provide better error messages for reverted transactions.
