Conditions for a native module to not be exposed to Javascript

I have a native iOS module that is suddenly not exposed anymore to Javascript. I'm using RN 0.59.4.

It seems that it happened after I renamed the iOS project.

What I can say is that I'm using dependency injection, not RCT_EXPORT_MODULE.

The module initialisation code is called, I've verified it by setting breakpoints in key areas such as requiresMainQueueSetup.

I guess my question is this: under which known conditions a module may not be exposed to JavaScript?

Any help appreciated.

EDIT 1: I've pinpointed the problem to RCTCxxUtils::createNativeModules() which at first receives 105 elements with my module, but is called a second time with only 104 elements.

EDIT 2: For what its worth, here are the back traces of each calls:

First Call => modules=105 elements in frame #0

EDIT 3: The first time, I have a call to registerExtraModules and this is where my module is added. The second time, a if condition is not satisfied, thus the extra module not added.

  if ([self.delegate respondsToSelector:@selector(extraModulesForBridge:)]) 

    {
        extraModules = [self.delegate extraModulesForBridge:_parentBridge];
      } else if (self.moduleProvider) {
        extraModules = self.moduleProvider();
      }

EDIT 4: I had to went back to the project before renaming and do it again to solve my problem. Today the problem is back again, this time as soon as I added a new native module.
