Firebase emulators:exec --only firestore not executing the script given as parameter

Question

I used to run the following command to run some tests against a emulated firestore instance:

firebase emulators:exec --only firestore 'npm test'

Since my upgrade to "firebase-functions": "^3.18.0" and `"firebase-functions-test": "^0.3.3"' this doesn't execute my tests anymore. And after a minute gives me: Error: TIMEOUT: Port 8080 on localhost was not active within 60000ms

Running firebase emulators:start --only firestore works fine. And if I change the command above to firebase emulators:exec --only auth 'npm test' the execution works as expected, but obviously the tests fail.

Does anyone have an idea on how to solve this?

@Gourav B, thanks for pointing me in the right direction. The problem only occurs with Node 17, with node 14 or 16 the execution runs fine! — dfinki, Feb 18 '22 at 15:47

As Gourav B asked me what node version I was on. I figured I would try to run it with different versions I had installed.

Version 17 was the default one, and would still not work. I quickly changed to 14 and the firebase emulators:exec --only firestore 'npm test' would run smoothly.

Also node version 16 doesn't have any problems.

As a tip to people reading this: To quickly switch between node versions I personally use Node Version Manager (nvm)

Indeed it was different node versions in the 2 terminal windows I had. Thank you – Benjamin Heinke Mar 15 '22 at 12:05

The reason for receiving this error in Firebase emulators might be due to a number of reasons. I would try to bring out all the possible solutions to resolve this through this answer.

Extend the duration of your Cloud Functions. Follow this.
You may try specifying the host as "127.0.0.1" instead of the default ‘localhost’. Firebase.json should look like this:

  { 
    "Firestore":
     { 
      "rules": "firestore.rules", 
      "indexes": "firestore.indexes.json"
     },
   "Emulators":
     { 
       "Firestore":
          { 
            "port": 8080, 
            "host": "127.0.0.1"
          }, 
      "Ui":
          { 
           "enabled": true
          }
       }
    }

Sometimes, reverting back to the previous version fixes, as suggested in the Stackoverflow case.
You could try running the Firestore emulator JAR directly and see if it works for you.

thanks for answering! as explained: firestore runs but the emulators:exec command doesn't run the specified script after starting firestore. due to emulators:exec the firestore-emulator waits for a minute and then exits, because no requests (from the script) have been made. – dfinki Feb 16 '22 at 09:23
You may have a look at this [Stackoverflow case](https://stackoverflow.com/questions/60996172/unable-to-connect-to-firebase-emulator-suite-with-exec). Let me know if that helps! – Mousumi Roy Feb 16 '22 at 11:21
it was because I was running it with node version 17. The command doesn't seem to work there yet. node 16 and below worked. Thanks for answering! – dfinki Feb 18 '22 at 15:54
