The client side formatters I prepared for wappler 5.0.4 and nodejs client side formatters do not work. The error messages returned and sample error messages are as follows .
Example formatter 1: This is an example previously prepared by @patrick and shared at the link below.
For me the custom formatters work. Please check in the network tab that they are actually loaded and the script tag should come after the one of dmxAppConnect.js.
You can also check in the console if the formatters are registered, then should be added under dmx.__formatters.string.
