The cost calculation fails with an expression

[AzizNgoueya]

Describe the bug When assigning a value containing an operation in the Options().max_execution_time, I got an error {"code":1208,"message":"Invalid job request body: Key: \\\'ProgramRunParams.Cost\\\' Error:Field validation for \\\'Cost\\\' failed on the \\\'min\\\' tag.","solution":"Check the JSON schema.","more_info":"https://cloud.ibm.com/apidocs/quantum-computing#error-handling"}

Steps to reproduce

options = Options()
options.max_execution_time = 4*60
sampler = Sampler(session = backend, options = options)
circuit = QuantumCircuit(1,1)
circuit.h(0)
circuit.measure_all()
job = sampler.run(circuit, shots = 1024) 

Expected behavior It should work

Suggested solutions

options.max_execution_time = 240 works

Additional Information

• qiskit-ibm-runtime version: 0.9.3
• Python version: 3.8.16
• Operating system: Mac OS

[merav-aharoni]

options.max_execution_time must be at least 300 seconds. So actually both versions should fail. I suggest we improve the error message.
