**Issue: SNS Testflight Deployment Fails with Panic on Testnet**
Hi ICP Community,
I am working on deploying my app on **Testnet** using **SNS Testflight**, and I have encountered an issue during the deployment process. Specifically, I am facing a **panic** when running the `dfx sns deploy-testflight` command. Below are the details of the issue:
**Error Details:**
When running the following command:
dfx sns deploy-testflight --init-config-file=“sns-init.yaml”
I receive the following error message:
thread ‘main’ panicked at /home/runner/.cargo/git/checkouts/ic-ca00ee28655ee32e/2dd2cce/rs/sns/cli/src/lib.rs:778:29:
dfx failed when called with args: [“canister”, “–network”, “local”, “install”, “–argument-type=raw”, “–argument”
The **backtrace** indicates that the panic occurs during the **`install_canister`** function in the SNS deployment process. The stack trace shows the error is happening in the following functions:
1. **`ic_sns_cli::call_dfx`**
2. **`ic_sns_cli::deploy::DirectSnsDeployerForTests::install_canister`**
3. **`ic_sns_cli::deploy_testflight`**
**Context and Observations:**
- I am deploying **on Testnet** and using **SNS Testflight** for my app's governance.
- The error happens when **installing the SNS canisters** during the deployment process. It appears that the program is panicking due to an issue with one of the canisters, likely related to the configuration or arguments being passed.
- **Neuron's fund participation** is enabled in my **`sns-init.yaml`** file, but as per the warning, this feature is not supported by SNS Testflight. I understand this is being ignored, but I am unsure if it is causing the issue.
- The `dfx` version I am using is **0.25.1**, and I have verified that all canisters are properly configured and allocated.
**What I’ve Tried:**
1. **Running with `RUST_BACKTRACE=1`**: This provided the stack trace above, which helped identify the location of the panic.
2. **Manually Installing Canisters**: I tried to manually install each canister using the command `dfx canister --network local install <canister_name>`, but the issue persists.
3. **Verifying Configuration**: I double-checked the `sns-init.yaml` file, especially the neuron settings and other parameters, ensuring there were no incompatible or unsupported configurations.
4. **Testing on Testnet**: Since I'm testing on the Testnet, I'm only testing **SNS Testflight** on Testnet for deployment, which should work but seems to be encountering issues during canister installation.
**Request for Assistance:**
I would greatly appreciate any insights or advice on how to resolve the issue. Specifically:
- Could the **Neuron's fund participation** being enabled in `sns-init.yaml` be affecting the deployment even though it’s not supported by SNS Testflight?
- Is there a known issue with **DFX 0.25.1** when deploying to Testnet with SNS Testflight?
- Are there any additional debugging steps or configurations I should check to ensure smooth deployment?
I am looking forward to your suggestions!
Thanks in advance for your help!
**Additional Information:**
- **DFX version**: 0.25.1
- **SNS version**: Testflight on Testnet
- **Error Stack Trace**: Provided above
- **SNS Initialization Config**: `sns-init.yaml` (can provide details if needed)
