In the ProposalCreated mappings, the condition for checking proposalDetails.type === "UpdateGlobalNftLimit" does not exist. And since the ProposalCreated mappings throw an error for unimplemented/unsupported proposal types, this mapping would throw an exception when the UpdateGlobalNftLimit proposal type is unfiltered (in future runtime upgrade) and a proposal is created of this type.
