[ANDROID] Invalid value for 'projectId': "undefined"

[DefiOfThrones]

Hello I'm trying to start a debug build of Metamask Android version but I'm facing an issue and I don't find any way to contact the Metamask Community (if there is one).

Describe the bug
Here is the exact error : [Error: Invalid value for 'projectId': "undefined"]

I suspect the fact that I didn't fill the file .android.env with but I'm not sure.
export MM_FOX_CODE=
export MM_BRANCH_KEY_TEST=
export MM_BRANCH_KEY_LIVE=
export MM_MIXPANEL_TOKEN=

If the issue is related, where can I find the values ?

hey @DefiOfThrones can you follow this format in your js.env file? https://github.com/MetaMask/metamask-mobile/blob/develop/.js.env.example

Hello,

Thx you for your reply, now I have a similar error without undefined.

I have encountered same issue. I did some digging. This started to occurring at this commit (infura v3 update) c74ce89. It started occurring because infura now throws exception if projectId is undefined or empty string. Quick and dirty workaround is in Engine.js

new NetworkController(
    {
	infuraProjectId: 'null', // instead of process.env.MM_INFURA_PROJECT_ID,

Root cause seems to be that .ios.env (and or .android.env, .js.env) variables are not being loaded

Logger.log(process.env);
>  [MetaMask DEBUG]: {"NODE_ENV": "development"}

even when changing .ios.env, .android.env, .js.env to

MM_FOX_CODE = 'null'
MM_BRANCH_KEY_TEST = 'null'
MM_BRANCH_KEY_LIVE = 'null'
MM_PUBNUB_SUB_KEY = 'null'
MM_PUBNUB_PUB_KEY = 'null'
MM_OPENSEA_KEY = 'null'
MM_INFURA_PROJECT_ID = 'null'

with or without export in front of the values. I ran yarn clean each time I change the values.

This is as far as I got, could not figure out why process.env does not load values from .ios.env, .android.env, .js.env

Update:

Upon further investigation I had to remove -- in (scrips/build.sh)

startWatcher() {
	source $JS_ENV_FILE
	if [ "$MODE" == "clean" ]; then
		watchman watch-del-all
		rm -rf $TMPDIR/react-*
		react-native start -- --reset-cache
	else
		react-native start
	fi
}

running yarn watch:clean then loads environment variables as expected. Only change needed is in .js.env export MM_INFURA_PROJECT_ID="null". This gets rid of the error at launch, but you will not be able to connect to actual networks.

• I made a note of this in READ.me so that Non-Metamask users don't get derailed by this.
• I changed default value to "null" in .js.env
• Created pull request

Hope this fix " No bulder URL present " for iOs
