Solidity编译成功，部署失败

Question

原本的程式码是可以编译后部署的，但我新增两个function之后，一样可以编译，也能在Remix的VM上成功部署，但如果切换成测试链：Goerli、BSC Testnet，部署就会报错：Failed transaction Transaction 2 failed! [ethjs-query] while formatting outputs from RPC '{"value": {"code": -32603,"data": {"message":"Internal Server Error"}}}'

新增两个function:searchCampaigns、getCampaignsByCategory，部署出现错误，请问到底是哪里有问题？

这可能是因为您在部署时没有提供足够的燃气费用，导致交易失败。尝试增加燃气费用并重新部署。此外，还要确保您正在使用正确的合约地址和 ABI。如果问题仍然存在，请检查您的智能合约代码是否与所选测试链的规则相符。
另外，如果您新增了两个函数而导致部署失败，那么问题可能出在这两个函数的实现上。您可以检查这两个函数的代码是否正确，并且确保它们符合 Solidity 语言的语法和规则。如果您无法解决问题，请提供更多的错误信息和您的智能合约代码，以便我们更好地帮助您解决问题。
