Hi,

I am trying to calibrate two event cameras to perform depth mapping through a stereo setup. I am passing in my own calibration.json file to the metavision_calibration_pipeline script to extract the intrinsics and extrinsics parameters of each camera. I can extract the intrinsics of each camera but when it comes to performing the "eb-synced-pattern-detected" step to extract the master to slave transform matrix by running

metavision_calibration_pipeline -i calibration.json

I get an error saying:

Executing step eb-synced-pattern-detection...
terminate called after throwing an instance of 'nlohmann::detail::type_error'
  what():  [json.exception.type_error.302] type must be string, but is number
Aborted (core dumped)

Ive attached the json file I am using to perform the eb-synced-pattern-detection step. If anyone has suggestions as to what can be causing this error, I would appreciate the help.
