openclaw - 💡(How to fix) Fix [Bug]: Chat history entries replaced with "chat.history omitted: message too large" after compaction [2 comments, 1 participants]

TL;DR

The issue can likely be mitigated by adjusting the compaction settings or message size limits to prevent replacement of chat history entries with the "[chat.history omitted: message too large]" placeholder.

Guidance

• Review the compaction settings in OpenClaw to see if there are any configurable options for message size limits or history retention that can be adjusted to prevent this issue.
• Check if there are any known issues or limitations in OpenClaw version 2026.4.15 related to chat history compaction and large messages.
• Consider testing with smaller chat messages or fewer messages to see if the issue is indeed related to message size or quantity.
• Investigate if there are any provider-specific settings or configurations (e.g., opencode) that may be contributing to this behavior.

Example

No specific code example can be provided without more information on the underlying implementation, but adjusting compaction settings might involve modifying configuration files or environment variables.

Notes

The exact solution may depend on the specifics of the OpenClaw configuration, the opencode provider, and the minimax 2.5 model, which are not fully detailed in the issue. Additionally, without access to the logs or more detailed error messages, it's challenging to provide a precise fix.

Recommendation

Apply workaround: Adjust compaction settings or message size limits to mitigate the issue, as upgrading to a potentially fixed version is not explicitly implied in the provided information.
