Setting CACHE_MEMORY_MAX env var crashes app #774
Description
I set the CACHE_MEMORY_MAX env var to 2000 and on application startup I got:
/mergeable/node_modules/lru-cache/index.js:36 throw new TypeError('max must be a non-negative number') ^ TypeError: max must be a non-negative number at new LRUCache (/mergeable/node_modules/lru-cache/index.js:36:13) at memoryStore (/mergeable/node_modules/cache-manager/lib/stores/memory.js:43:20) at Object.create (/mergeable/node_modules/cache-manager/lib/stores/memory.js:235:16) at Object.caching (/mergeable/node_modules/cache-manager/lib/caching.js:32:47) at new Cache (/mergeable/lib/cache/cache.js:22:35) at Object.<anonymous> (/mergeable/lib/configuration/configuration.js:8:22) at Module._compile (node:internal/modules/cjs/loader:1469:14) at Module._extensions..js (node:internal/modules/cjs/loader:1548:10) at Module.load (node:internal/modules/cjs/loader:1288:32) at Module._load (node:internal/modules/cjs/loader:1104:12)Looks like this can be fixed by parsing the env var as an int using something like:
function getMemoryMax () { return process.env.CACHE_MEMORY_MAX ? parseInt(process.env.CACHE_MEMORY_MAX) : undefined }Happy to open a PR.
