Qiskit code: function BaseAnalysis.run.<locals>.run_analysis is failed

Question

when I run my qiskit code as below on azure,

circ_1a = QuantumCircuit(1)
circ_1a.h(0)
exp_1a = StateTomography(circ_1a)
data = ExperimentData(experiment = exp_1a)
data.add_data(jobs)
data = exp_1a.analysis.run(data)

it always shows me an error like this: even this code works for other people, but it didn't work for my workspace

Analysis callback <function BaseAnalysis.run.<locals>.run_analysis at 0x7f8246ab6dd0> failed:
Traceback (most recent call last):

    metadata = datum["metadata"]
KeyError: 'metadata'

Does anyone know what's this problem?
