✔  Deploy complete!

As you can see, there is no function called "ssrcasavelerosbotevbl", so I guess the issue is not with my functions.

Then for some reason when I run

firebase deploy --only hosting

The command build my web, then it tries to deploy hosting AND functions, when I explicitly said --only hosting.

Well this behavior has been the same since day 1 with this project (in other projects I'm able to only upload/update my website), but it has not been an issue till 3 days ago, when I try to do the firebase deploy --only hosting, this is the console output:

Functions deploy had errors with the following functions:
    firebase-frameworks-casavelerosbot-evbl:ssrcasavelerosbotevbl(us-central1)
i  functions: cleaning up build files...

Error: There was an error deploying functions

So I don't know why it is asking for a ssrcasavelerosbotevbl function. I have removed that function a long time ago.

So because of the behavior an this error, I am not able to update my webpage

Answer 1

Solved by adding maxInstances to my firebase.json

{
  "functions": {
"source": "functions"
  },
  "hosting": {
    "source": ".",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "frameworksBackend": {
      "region": "us-central1",
      "maxInstances": 2
    }
  }
}
