# Support {% hint style="info" %} If you have a question, you can ask the community in the [**Clockwork Discord**](https://discord.gg/6zGyWF7mP4). If you would rather have a private word with the team, please file a ticket in the support channel. {% endhint %} ## Why is my thread not executing? * Is your thread funded account with enough SOL? Check it's balance and airdrop some SOL to it. See the [**Fees**](broken://pages/heRJ0TIWgVkFnmIHeFWk#fees) section for more information. * Is your thread paused? Check its status in the [**Clockwork explorer**](https://app.clockwork.xyz/?cluster=devnet). * Check for programming errors. Use the [**Clockwork explorer**](https://app.clockwork.xyz/?cluster=devnet) to browse for your thread and click the check if your thread is able to simulate your instructions without errors. #### Common errors > InstructionDidNotDeserialize and others Serialization errors can happen when there is a mismatch between your validator's clockwork engine version and the clockwork libraries you are using. Naturally these two need to match: * Note the version of your `clockwork-client` * Note the version of your `clockwork-sdk` * Make sure to checkout and run the same version of the clockwork engine. > (code -32002) Transaction simulation failed: Attempt to load a program that does not exist This often happens on localnet. You are probably trying to create a thread by calling the thread program, but that program cannot be found. This is most likely due to running `solana-test-validator` or `anchor localnet` instead of `clockwork localnet`. > I see in the validator logs: "Expected an executable account" You created a thread, but that thread is trying to execute an instruction whose program does not exist (hence the not an executable account). You haven't deployed your program yet. ## How can my instruction pay for account initialization? ## Why is localnet not working? > My validator stopped after ⠚ Initializing.. The Clockwork plugins depends on a specific of Solana *(for know we recommend that you use the exact same version)*. Make sure your Solana validator uses the same version as Clockwork by installing it again if needed `solana-install init x.y.z`. * Check the [**release notes**](https://github.com/clockwork-xyz/clockwork/releases) in doubt. * If for some reason you cannot install the same version, please talk to us. > How do I know which version of Solana the Clockwork Engine (geyser plugin) depends on? Run `cat test-ledger/validator.log | grep "crate-info"` ## How do I write a cron schedule? The easiest way to test your cron string before even playing with thread, is to install the [**clockwork-cli**](https://docs.clockwork.xyz/reference/pages/88JvRfSOzBnFrXcdVKNo#1.-install-the-clockwork-cli) and run `clockwork crontab YOUR_STRING`. You can use [**https://crontab.guru**](https://crontab.guru/) as reference to build your cron string. Note that crontab guru is a 5 columns cron while the Clockwork [**cron parser**](https://github.com/clockwork-xyz/clockwork/tree/main/cron) is a 7 columns cron. It includes **seconds** (left most column) and **year** (right most column). ### Anchor 0.28 We don't support anchor 0.28 yet, if you encounter build issue related to - * AnchorDeserialize not implemented * spl-token-2022 failed to compile Please check these two solutions: {% embed url="" %} {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
