Configuration file for Pages projects does not support "observability"

I'm trying to get my worker project working with observability via the documentation

compatibility_date = "2024-11-12"

[observability]
enabled = true
head_sampling_rate = 1

compatibility_date = "2024-11-12"

[observability]
enabled = true
head_sampling_rate = 1

compatibility_date = "2024-11-12"

[observability]
enabled = true
head_sampling_rate = 1

compatibility_date = "2024-11-12"

[observability]
enabled = true
head_sampling_rate = 1

I have the latest version of wrangler: 3.87.0

However I get this error: Configuration file for Pages projects does not support "observability"

I have checked

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json and observability is in there, I have also tried closing and reopening the app as well as wiping out node_modules and installing again.

Just checked the file at node_modules/wrangler/wrangler-dist/cli.jsnode_modules/wrangler/wrangler-dist/cli.js

Looks like a bug:

var supportedPagesConfigFields = [
  "pages_build_output_dir",
  "name",
  "compatibility_date",
  "compatibility_flags",
  "send_metrics",
  "limits",
  "placement",
  "vars",
  "durable_objects",
  "kv_namespaces",
  "queues",
  // `producers` ONLY
  "r2_buckets",
  "d1_databases",
  "vectorize",
  "hyperdrive",
  "services",
  "analytics_engine_datasets",
  "ai",
  "version_metadata",
  "dev",
  "mtls_certificates",
  "browser",
  // normalizeAndValidateConfig() sets this value
  "configPath",
  "upload_source_maps"
];

var supportedPagesConfigFields = [
  "pages_build_output_dir",
  "name",
  "compatibility_date",
  "compatibility_flags",
  "send_metrics",
  "limits",
  "placement",
  "vars",
  "durable_objects",
  "kv_namespaces",
  "queues",
  // `producers` ONLY
  "r2_buckets",
  "d1_databases",
  "vectorize",
  "hyperdrive",
  "services",
  "analytics_engine_datasets",
  "ai",
  "version_metadata",
  "dev",
  "mtls_certificates",
  "browser",
  // normalizeAndValidateConfig() sets this value
  "configPath",
  "upload_source_maps"
];

Shouldn't observability be a key in here?

Cloudflare Pages just doesn't support observability and there's no plans for it to do so workers-observability

disconditionOP•11/15/24, 10:08 PM

Oh really? Thanks I had no idea

Chaika•11/15/24, 10:09 PM

yea Pages probably isn't going to see many new things, Workers Assets is the new thing/replacement, built directly into Workers, they're working on migration pathways from Pages -> Workers Assets

Nice, looking forward to it
