Hi @technicallyty, thanks for opening the issue. Based on your comment this looks like a duplicate issue of #1352. Is that correct? I believe it is expected that a panic will occur if an SDK module does not have its state initialized |

sort of - i'm moreso concerned with the panic on empty state during ExportGenesis, if that gets fixed by changing the param get method used or implementing sims -- either would suffice for me
modules in the SDK commonly have panic-safe code when getting params for |

We will implement sims for >= v5 and then second concern will be addressed when we migrate our params to be self managed #2010 I believe the SDK traditionally panic'd on unset params (this is from v0.46.1) and that this behaviour changed when it migrated to self managed params. I agree this behaviour is incorrect as one should not cause ExportGenesis to panic. It seems like a very unlikely edge case as the app.go would have to be misconfigured (not calling app.mm.InitGenesis) so I don't see reason to prioritize this change |

Summary of Bug
If no initial state is given to the module, calling ExportGenesis on the module, or the app in general, will cause a panic, due to this line, which gets the params from the paramKeeper subspace.
subspace.Getcauses a panic if the parameter does not yet exist.Expected Behaviour
ExportGenesis should not panic if the module has no state. It might be more preferable to use
GetIfExistswhen getting the parameters for exporting state to prevent such errors.Version
v5
