Hey @jenkin2120! 👋 I'm here to help you out with bugs, questions, and becoming a contributor. Let's squash this bug together!
I found a similar issue that was previously reported and closed. The error message you're encountering indicates that the variable size exceeds the limit defined in the configuration (dify_config.MAX_VARIABLE_SIZE
). The default limit is set to 5120 bytes, and your variable size is 5350 bytes, which is causing the VariableError
to be raised.
To resolve this, you can either:
MAX_VARIABLE_SIZE
limit: If reducing the variable size is not feasible, you can increase the MAX_VARIABLE_SIZE
limit in your configuration.To modify the MAX_VARIABLE_SIZE
in your Docker deployment for Dify, follow these steps:
Edit the docker-compose.yaml
file:
Add or update the MAX_VARIABLE_SIZE
environment variable under the appropriate service's environment section. For example, if it needs to be set for the api
service, you would add it like this:
api:
image: your-api-image
environment:
MAX_VARIABLE_SIZE: ${MAX_VARIABLE_SIZE:-default_value}
# other environment variables
Replace your-api-image
with the actual image name and default_value
with the desired default value for MAX_VARIABLE_SIZE
.
Update the .env
file:
Ensure that your .env
file includes the MAX_VARIABLE_SIZE
variable. You can do this by copying the .env.example
file to .env
and then adding or modifying the MAX_VARIABLE_SIZE
entry:
cp .env.example .env
Then, edit the .env
file to include:
MAX_VARIABLE_SIZE=your_desired_value
Restart your Docker containers: After making these changes, restart your Docker containers to apply the new environment variable:
docker compose down
docker compose up -d
By following these steps, you can increase the MAX_VARIABLE_SIZE
limit to accommodate larger variables in your Dify application. This should help resolve the error you're encountering [1].

For docker, please check the .env
in this folder docker/
.
Thanks! I did as Dosu @dosu says, It works, I am continuously monitoring the operation status. I hope MAX_VARIABLE_SIZE variable can be writen into the section 'api' of docker-compose.yaml file explicitly later. Thank you once again.
Hey @jenkin2120! I'm glad to hear that the solution worked for you and that you're keeping an eye on things. As for your suggestion about the MAX_VARIABLE_SIZE
variable, that's a great idea! However, I'm just a bot here to help with bugs, technical questions, and engineering knowledge. If you think this should be addressed, you might want to reach out to the Dosu Team to share your feedback. They'll be happy to hear from you! 😊

Steps to reproduce
1.Designed a chatflow with two steps of qwen2.5, and chat memory settings is disable; 2.The first LLM prompt length is 3300+ characters, the second LLM prompt length is more 4000+; 3.When start a new conversation,first question is replayed perfectly, but second question prompt: variable size 5350 exceeds limit 5120 in the dialog page, Retry third、forth question prompt same error. 4.I searched content: 'raise VariableError(f"variable size {result.size} exceeds limit {dify_config.MAX_VARIABLE_SIZE}")' in the file 'variable_factory.py' should matching above error, but MAX_VARIABLE_SIZE is set in .env, and the value is 204800. 5.I searched all files with content 5120, but nothing found related to it.
✔️ Expected Behavior
pls check the reson of the error: variable size 5350 exceeds limit 5120, and fix the bug
❌ Actual Behavior
