We've encountered several errors that are likely related to the RPC node and possibly the vault contract itself.
Here's a summary of the observed issues:
1. **Gas Estimation Failure:**
* The primary error is related to gas estimation. We are seeing the following error in the browser's console:
* `ContractFunctionExecutionError: RPC Request failed. Details: the method eth_estimateGas does not exist/is not available`
* This indicates that the RPC node being used by the Steer frontend is not supporting the necessary `eth_estimateGas` method, which is essential for estimating transaction gas costs.
* This error is preventing withdrawals.
* Steer is using the following RPC node (as reported in the errors): `https://evmos.drpc.org`
2. **CORS Error:**
* We're also seeing a CORS (Cross-Origin Resource Sharing) error:
* `Access to fetch at 'https://evmos.api.onfinality.io/public' from origin 'https://app.steer.finance' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains the invalid value 'api.onfinality.io'.`
* This means that the Steer website is unable to fetch data from the `https://evmos.api.onfinality.io/public` API endpoint because the server is not configured to allow requests from `app.steer.finance`.
3. **Contract Function Reverted:**
* In addition to the above errors, the `vaultDetailsByAddress` function call is reverting, which is indicative of a problem on your side.
**Action Requested:**
1. **Address the `eth_estimateGas` Error:** This is the most critical issue. Please investigate the RPC node being used and ensure it supports the `eth_estimateGas` method. If the current node does not support it, please switch to a different RPC node that does.
2. **Fix the CORS Issue:** Please correct the `Access-Control-Allow-Origin` header on the `https://evmos.api.onfinality.io/public` endpoint to allow requests from `https://app.steer.finance`.
3. **Investigate the Reverted Function:** Please have a look at the `vaultDetailsByAddress` function failure.

On the Steer site, when I try to withdraw, in the console I get these errors:

```
**1. Withdrawal Errors on Steer's Webpage**
* **"Disable simulation" Error:**
* **Error:** `Error on withdraw Error: Disable simulation`
* **Meaning:** This suggests that Steer's website has a mechanism to simulate transactions (to estimate gas costs, etc.) and that this simulation is being disabled. This is not a fatal error, but it might indicate that the website is not able to fully estimate the gas costs for the withdrawal. It's a warning, not a direct cause of the failure.
* **CORS Policy Error:**
* **Error:** `Access to fetch at 'https://evmos.api.onfinality.io/public' from origin 'https://app.steer.finance' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: The 'Access-Control-Allow-Origin' header contains the invalid value 'api.onfinality.io'.`
* **Meaning:** This is a *CORS (Cross-Origin Resource Sharing)* error. It means that the Steer website (running from `https://app.steer.finance`) is trying to make a request to `https://evmos.api.onfinality.io/public`, but the server at `evmos.api.onfinality.io` is not configured to allow requests from `app.steer.finance`.
* **Cause:** This CORS error is a *server-side* issue. The server at `evmos.api.onfinality.io` needs to be configured to include the correct `Access-Control-Allow-Origin` header in its responses. In this case, it seems the header is set to `api.onfinality.io`, which is not correct. It should allow origin `app.steer.finance`.
* **Impact:** This CORS error can prevent the Steer website from fetching data from `evmos.api.onfinality.io`. This could affect the withdrawal process if the website needs to fetch data from that API.
* **`eth_estimateGas` Error:**
* **Error:** `Uncaught (in promise) ContractFunctionExecutionError: RPC Request failed.` followed by `Details: the method eth_estimateGas does not exist/is not available`
* **Meaning:** This is a critical error! The website is trying to estimate the gas cost for the withdrawal transaction by calling the `eth_estimateGas` method on an RPC (Remote Procedure Call) node. However, the RPC node at `https://evmos.drpc.org` is reporting that the `eth_estimateGas` method is *not available*.
* **Cause:** This is a problem with the RPC node that Steer's website is using. It indicates that the RPC node either:
* Does not support the `eth_estimateGas` method.
* Is not correctly configured to handle gas estimation requests.
* **Impact:** The website *cannot* estimate the gas cost for the withdrawal, which is a crucial step before submitting the transaction. This is a *major* problem.
* **`vaultDetailsByAddress` Reverted:**
* **Error:** `ContractFunctionExecutionError: The contract function "vaultDetailsByAddress" reverted.`
* **Meaning:** This is the most direct indication of a problem. The website is trying to call the `vaultDetailsByAddress` function on a contract and it's reverting. Reverting means the function call failed.
* **Cause:** The `vaultDetailsByAddress` function is failing. The error suggests that something is wrong with the vault contract, the arguments being passed, or the state of the blockchain.
* **Impact:** Prevents the function from being called successfully.
**2. Recommendations**
* **CORS Error:** The CORS error needs to be fixed on the `evmos.api.onfinality.io` server. Contact the Steer team to report this.
* **`eth_estimateGas` Error:** This is the *most critical* issue. Report this to Steer. They need to switch to an RPC node that supports the `eth_estimateGas` method, or they need to find a workaround. This is likely the reason why your withdrawals are not working.
---
**Interface Link and Console Details**
* I have created a withdrawal interface that demonstrates the issue. You can access it here: https://poetic-zuccutto-c18b26.netlify.app
* Here is the relevant console output from my interface when attempting a withdrawal. I am using the RPC node from https://evmos.lava.build
