In `@docker-compose.sample.yml`:
- Line 125: Update the Jaeger Web UI port mapping in the Docker Compose
configuration to bind host port 16686 explicitly to 127.0.0.1 instead of all
host interfaces, preserving container port 16686.
- Around line 106-107: Remove the OTLP gRPC and HTTP host port mappings for 4317
and 4318 from the sample Docker Compose configuration, keeping the receiver
accessible only through the container or private network.
- Around line 101-102: Update the otel-collector service configuration to
inherit Floware’s AWS credential source and mount the host’s GCP Application
Default Credentials for local runs, while retaining AWS_REGION and
GOOGLE_CLOUD_PROJECT. Document the required local credential setup so selecting
aws.yaml or gcp.yaml provides the collector with usable cloud credentials.
- Around line 111-118: Update the collector healthcheck to use a probe
executable available in the configured OpenTelemetry Collector image, or
switch/build the collector image to include the required client; preserve the
existing endpoint and healthcheck timing while ensuring service_healthy
dependencies can become ready.
In `@OPENTELEMETRY_ARCHITECTURE_GUIDE.md`:
- Around line 109-114: Replace all machine-local
file:///home/aquib/workspace/rootflo/wavefront targets in
OPENTELEMETRY_ARCHITECTURE_GUIDE.md, including the exporter links and the
additional referenced sections, with repository-relative links that resolve
correctly in GitHub and packaged documentation.
In `@otel/exporters/honeycomb.yaml`:
- Line 11: Update the otlphttp/cloud endpoint configuration to fall back to
https://api.honeycomb.io when OTEL_CLOUD_ENDPOINT is unset, preserving any
explicitly configured endpoint.
In `@otel/exporters/otlphttp.yaml`:
- Around line 25-27: Require OTEL_CLOUD_ENDPOINT to use HTTPS before deployment
and configure the exporter so insecure HTTP redirects cannot be followed. Apply
this validation and redirect protection at both otel/exporters/otlphttp.yaml
lines 25-27 and otel/exporters/honeycomb.yaml lines 11-13, preserving credential
injection only for secure endpoints.
In
`@wavefront/server/modules/common_module/common_module/telemetry/baggage_middleware.py`:
- Line 61: Update the baggage-setting logic in the telemetry middleware so
app.session.id, app.user.id, and app.role.id are not added to the active
OpenTelemetry baggage context; retain them as local span attributes or exclude
baggage from the outbound propagator while preserving propagation for

Provide cloud credentials to otel-collector.
When a local Compose run selects aws.yaml or gcp.yaml without a runtime identity, the collector receives only AWS_REGION or GOOGLE_CLOUD_PROJECT. Floware’s AWS variables and GCP credential mount are not inherited by the collector, so the cloud exporters can fail to send telemetry. Add a collector-specific AWS credential source and GCP Application Default Credentials mount, and document the local setup.

Provide a default Honeycomb endpoint.
OTEL_CLOUD_ENDPOINT is documented as optional for the US endpoint, but the env provider returns an empty value when it is unset. Collector 0.159.0 then rejects otlphttp/cloud because no endpoint is configured. Use ${env:OTEL_CLOUD_ENDPOINT:-https://api.honeycomb.io}, or require the variable in the selection instructions.

OpenTelemetry Collector Contrib v0.159.0 OTTL SHA256 function non-string conversion error_mode ignore behavior
💡 Result:
In OpenTelemetry Collector Contrib v0.159.0, the OTTL SHA256 function is specifically designed to accept a string argument [1]. If it receives a non-string value, the behavior depends on the error_mode configuration of the processor (such as the transform processor) where the function is executed [2][3]. When the error_mode is set to ignore, the processor logs the error resulting from the invalid input (such as a type mismatch for the SHA256 function) and proceeds to the next statement in the pipeline [2][3]. This prevents the telemetry payload from being dropped due to the error [2][3]. As of v0.159.0, the error_mode in the transform processor defaults to ignore [3][4], following the promotion of the processor.transform.defaultErrorModeIgnore feature gate to stable [5]. Summary of error_mode behaviors: - ignore: Errors are logged, and processing continues with the next statement [2][3]. This is the recommended mode [2][3]. - silent: Errors are suppressed (not logged), and processing continues with the next statement [2][3]. - propagate: The error is returned up the pipeline, which typically results in the telemetry payload being dropped [2][3].

OpenTelemetry Collector Contrib v0.159.0 OTTL SHA256 function implementation error return non-string set statement
💡 Result:
There is no documented error in OpenTelemetry Collector Contrib v0.159.0 specifically related to the SHA256 function returning a non-string value within a set statement [1][2][3]. The SHA256 function in the OpenTelemetry Transformation Language (OTTL) is designed to operate on string values [4]. As implemented, it takes a target (a StringGetter), hashes the input string, and returns the hex-encoded string representation of the SHA-256 hash [4]. Because it is explicitly typed to handle string inputs and return a string value, it inherently avoids returning non-string types when used correctly [4]. In OTTL, the set(target, value) statement requires the value to be compatible with the target field [5]. If a converter function like SHA256 is used, it must provide a type that the target field can accept [5]. Historical guidance for OTTL functions indicates that if a function returns an incompatible type or nil, it will trigger an error, and the behavior of that error is governed by the configured ErrorMode [5]. If you are encountering an error, ensure that: 1. The input to the SHA256 function is indeed a string. 2. The target field of your set statement is capable of storing a string value. No regression or bug regarding this specific interaction was identified in the v0.159.0 release notes [1][2]. If you are experiencing unexpected behavior, it is recommended to verify your configuration against the current documentation or open an issue on the OpenTelemetry Collector Contrib GitHub repository if you believe you have discovered a bug [6][2].

Guard SHA256 before forwarding cloud telemetry.
The collector exposes unauthenticated OTLP ports, so a producer can submit a numeric or boolean app.user.id. Since SHA256 accepts strings only and error_mode: ignore skips the failed assignment, the raw value reaches the cloud exporter. Delete non-string values and hash only values guarded by IsString(...).
