deployment failing with "Error An unknown error occured."

Questions / Help Build debugging

I don’t see any further hints for debugging. What can I do to resolve this?

Also, “occurred” has two Rs. :slight_smile:

==> Verifying app config
--> Verified app config
==> Building image
Remote builder fly-builder-aged-field-2073 ready
==> Creating build context
--> Creating build context done
==> Building image with Docker

Can you paste your fly.toml? Looks like your metrics block may be formatted incorrectly.

Ah, we did add that recently. Is this enough to work from?

app = "REDACTED"

kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[deploy]
  # REDACTED

[env]
  # REDACTED

[experimental]
  # TODO: do we need this?
  allowed_public_ports = []
  auto_rollback = true

[[statics]]
  # REDACTED

[[statics]]
  # REDACTED

[[statics]]
  # REDACTED

[[services]]
  # REDACTED

[[services]]
  # REDACTED

[[metrics]]
  port = 9091
  path = "/metrics"

Try changing to [metrics] in single brackets.

Bingo! Guess I found a new corner case for you to un-unknown an error. :slight_smile:

Is there a tool I can use to validate a fly.toml short of doing a full deploy?

Believe it or not, the only tool we have now is the Even Better TOML VSCode extension. Behind the scenes, that just uses a JSON schema. We haven’t gotten around to using this for validation in flyctl yet.
