Hi @Ranran-bugmaker! I'm Dosu and I’m helping the dify team.

The "not supported value type integer" error in Dify v1.10.1 happens because older versions enforce strict type matching for variables—if you initialize a variable as an integer, assigning a float (like 1.0654546) will trigger a type error. This is a known issue and has been fixed in newer versions.

To resolve this, upgrade to any Dify version released after November 13, 2025, which includes the fix from PR #27954 and further improvements for integer/float handling in workflows. The latest versions also include robust support for both integer and float types in variable assignment and workflow logic (PR #29035).

If you can't upgrade right away, a workaround is to set your variable's default value to a float (e.g., 0.1) if you expect to assign floats, or store values as strings and convert them in your workflow logic. But upgrading is the recommended and permanent solution.

If you still see the error after upgrading, double-check that your variable types and assigned values match, or let me know for further troubleshooting.

To reply, just mention @dosu.
