@dosubot[bot] commented on GitHub (Dec 29, 2025):

You can increase CODE_MAX_STRING_LENGTH in your .env file, but the only documented value in the Dify repo is 400000, as shown in the .env.example file. There are no hardcoded limits in the codebase, so technically you can set it higher, such as 800000. However, the actual upper bound may depend on the sandbox service implementation and your system's available resources. Be aware that setting a much higher value could impact performance or memory usage, so test carefully in your environment.
Reference: .env.example
