Wrong JSON output from SchemaErrors.message

[Twomasz]

Description

The column field does not show the column name itself. Instead, it duplicates the schema name.

So far I have only seen this problem in errors under the SCHEMA key in JSON output message. All errors under the DATA key have the column names displayed correctly.

• I have checked that this issue has not already been reported.
• I have confirmed this bug exists on the latest version of pandera.
• (optional) I have confirmed this bug exists on the main branch of pandera.

Code Sample, a copy-pastable example

df = pd.DataFrame({
    'defined_in_schema': [1, 2],
    'undefined_in_schema': [3, 4],
})

schema = pa.DataFrameSchema(
    columns={
        "defined_in_schema": pa.Column(dtype="int64", name="defined_in_schema"),
    },
    name='MySchemaName',
    strict=True,
)


try:
    df_val = schema.validate(df, lazy=True)
except pa.errors.SchemaErrors as exc:
    print(exc)

Output in the console

{
  "SCHEMA": {
    "COLUMN_NOT_IN_SCHEMA": [
      {
        "schema": "MySchemaName",
        "column": "MySchemaName",
        "check": "column_in_schema",
        "error": "column 'undefined_in_schema' not in DataFrameSchema {'defined_in_schema': <Schema Column(name=defined_in_schema, type=DataType(int64))>}"
      }
    ]
  }
}

Expected behavior

The output of this code should contains "column": "undefined_in_schema" instead of "column": "MySchemaName"
