We are getting intermittent 500 Status codes whenever we call the following endpoint /Person-With-Significant-Control, usually if we call the same endpoint with the same payload a second time the issue stop occurring. This only applies to the sandbox environment provided by company house.
The following screenshot provides details on the time this error occurred which may help identify the origin on the issue on your side.
NOTE: I tried to provide more details in the form of screenshots however as I am a new user can only post one.
Thanks
