[Bug] Adding something to `Object.prototype` leads to "unknown non-custom strategy for compiling constraint derivation function"

[KaKi87]

Hi,

My project depends on find-my-way through fastify.

For debugging purposes that have nothing to do with either of those, I wanted to temporarily add the following into my code :

Object.prototype.tap = function(fn) { fn(this); return this; };

But suddenly, I encountered the following error :

Error: unknown non-custom strategy for compiling constraint derivation function
   at Constrainer._buildDeriveConstraints (node_modules/find-my-way/lib/constrainer.js:159:17)
   at Constrainer.noteUsage (node_modules/find-my-way/lib/constrainer.js:88:14)

   at Object._get [as get] (node_modules/fastify/fastify.js:261:34)

I also tried the following but it didn't change anything :

Object.defineProperty(Object.prototype, 'tap', { enumerable: false, value: function (fn) { fn(this); return this; }});

Thanks
