Output values not encoding properly

[thclark]

In the yuriyfoil demo, the following code:

    # Assign to the analysis outputs
    for key, value in zip(('cl', 'cdp', 'cdv', 'cp_x', 'cp'), results):
        # TODO see issue 
        analysis.output_values[key] = value

Results in:

analysis-fa8f9ad9-8c01-4709-8e46-54ee8aada52d ERROR 2020-10-06 22:52:29,699 runner 1 140199177582336 array([0.25859084]) is not of type 'array'

Failed validating 'type' in schema['properties']['cl']:
    {'description': 'Output cl values corresponding to input alpha values',
     'items': {'type': 'number'},
     'title': 'cl',
     'type': 'array'}

On instance['cl']:
    array([0.25859084])

It's fixed by manually casting the numpy arrays to lists:

    # Assign to the analysis outputs
    for key, value in zip(('cl', 'cdp', 'cdv', 'cp_x', 'cp'), results):
        # TODO see issue
        analysis.output_values[key] = value.tolist()

Clearly, the output isn't getting correctly passed through the encoder

It's to do with the outputs of the validation not being placed into the analysis object that gets returned from the runner:

            self.twine.validate(output_values=analysis.output_values)
            self.twine.validate(output_manifest=analysis.output_manifest)

        except Exception as e:
            analysis_logger.error(str(e))
            raise e

        return analysis

Here in twined server are the consequences of not getting properly serialised output. One has to convert it...
