When we bootstrap the data in OutSystems, the platform is comparing column header and entity attributes and creating a bootstrap logic based on that. But if any one of the cell data is not matching the entity attribute datatype (for eg; entity attribute type = email, value in excel =hathimary) , bootstrapping is not happening and no error logged in service center as well. It would be good to validate the data as well while bootstrapping or log the error with excel row and column index information. It will allow the developer to correct the data and successfully bootstrap.
