# [DEPRECATED] Undefined is not an object evaluating `register_handler_fx`
|
|
|
|
## Deprecation note
|
|
|
|
This type of error should not occur anymore now that we require the namespace in the `fx.cljs` file.
|
|
|
|
It can however happen with other macros requiring a cljs namespace.
|
|
|
|
The general fix for that type of issue is to have two files for the namespace where your macros are defined, let's say for `my-project.my-macro` namespace you would have:
|
|
- my_macro.cljs in which you need `(:require-macros my-project.my-macro)` and `(:require my-project.the-namespace-used-in-the-macro)`
|
|
- my_macro.clj in which you define the macro
|
|
|
|
That way you don't need to use any magical call like `find-ns` or inline `require` with some kind of call only once switch (which was the root cause of another bug in ``defstyle`` macro because the compilation phase at which the evaluation of the switch is done was not properly considered).

## Cause
|
|
|
|
- stacktrace mentions `register_handler_fx`,
|
|
- common cause is when requires have been cleaned up and a require of `status-im.utils.handlers` namespace was removed because it looked like it was unused but was actually used through a fx/defn macro
|
|
|
|
## Solution
|
|
|
|
go through known faulty commit looking for deleted requires
