should probably also add an if statement for cronConfig.swapEnabled in the

trigger.ts server - https://github.com/GaloyMoney/galoy/blob/main/src/servers/trigger.ts#L409-L412

[dolcalmi]

this should be part of service validation

[dolcalmi]

probably here should be the validation, also service should not throw exceptions. Please check onchain service as example

@dolcalmi thank you for the comments, will copy the over to #1891 which replaced this PR to be on a GaloyMoney branch
