JSON serializable error

[atul20027]

when i m submitting the option_0 and option_1 to the grade_lab4_ex7 ... it is giving the error

TypeError: Object of type UnsetType is not JSON serializable

[jgs03177]

The grader checks the following parameters:

options.resilience_level,
options.dynamical_decoupling.enable,
options.dynamical_decoupling.sequence_type,
options.default_shots,
options.optimization_level

However, some parameters are Unset, which the grader cannot read. Try setting all the parameters.

@jgs03177 Considering I turn options.dynamical_decoupling.enable to False, what should I put in options.dynamical_decoupling.sequence_type, it seems it's required anyway

I tried set all required parameters, but the answer was incorrrect. Do you guys know what wrong in my case? Thank you for your reading.

@vantnprof "XpXm" in dd sequence type for option_0 worked for me

Thanks for your sharing. It worked!
