step pattern parse error

[EugeneJao]

i use ollama to run my model qwen3-vl:8b. But when i run the example, there are some exception show on ollama log. i search the key words on the porject and found the template defined in the output_schemas.py line 251. finally，i modified the wrong regex，and it work！
git commit id : 1a067a1

wrong code

                  "step_id": {
                        "type": "string",
                        "pattern": "^Step \\d+$"
                    },

correct code
"step_id": {
"type": "string",
"pattern": "^Step \\d+$"
},

Actually，the commit you paste here have not any diff with OutputSchemas, and your correct code seems have not change with the wrong code you paste. Do you mean change the "\d" to "[0-9]"?
