[Docker CLI] 'error getting credentials - err: exec: "docker-credential-desktop": executable file not found in $PATH' — config.json credsStore points to a missing helper

Cause (Documented platform behavior): The CLI executes docker-credential-<credsStore> from PATH to fetch credentials; Docker requires the helper to be in the client's PATH. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor):

[Docker CLI] 'permission denied while trying to connect to the docker API at unix:///var/run/docker.sock' — user not in docker group / group not active in agent shell

Cause (Documented platform behavior): Docker daemon socket access is limited to root and members of the docker group; group membership is evaluated at login. Fix status: documented_behavior Misleading approaches: - chmod 666 /var/run/docker.sock — works but opens root-equivalent

[boto3/botocore] 'botocore.exceptions.NoRegionError: You must specify a region.' in fresh containers/CI — no AWS_REGION/AWS_DEFAULT_REGION or profile region

Cause (Documented platform behavior): Regional services need a region to build the endpoint; credentials don't carry one. Fix status: documented_behavior Limitations: - Which env var each non-Python SDK reads is not covered by the cited source. Evidence (public sources, summarize

[DBOS Python] Duplicate workflow IDs / dedup: "Workflow ID X is already in use by workflow Y with status Z." and "was deduplicated due to an existing workflow in queue"

Cause (Documented platform behavior): Workflow IDs are idempotency keys; deduplication IDs allow one active workflow per queue+ID. Fix status: documented_behavior Other error fragments: - was deduplicated due to an existing workflow in queue {queue_name} with deduplication ID {de

[Instructor] "token_budget is not supported for xAI requests"

Cause (Documented platform behavior): The xAI provider client pops token_budget and raises because it cannot track cumulative usage for it. Fix status: documented_behavior Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.c

[bitsandbytes] "Attempted to use bitsandbytes native library functionality but it's not available" (successor of legacy "CUDA Setup failed despite GPU being available") in QLoRA/8-bit runs

Cause (Documented platform behavior): The loader defers the failure until a native method is called; it picks the library by torch.version.cuda and falls back only within the same CUDA major version. Legacy releases printed "CUDA Setup failed despite GPU being

[AWS SDKs in containers on EC2/EKS] 'Unable to locate credentials' (NoCredentialsError) — IMDSv2 PUT response hop limit 1 blocks pods/docker containers; botocore IMDS timeout 1s x 1 attempt

Cause (Documented platform behavior): Intentional default hop limit of 1 on EC2; EKS-provisioned nodes (eksctl/official templates) set 2. Fix status: documented_behavior Misleading approaches: - Raising SDK timeouts alone doesn't help when the hop limit drops the PUT response. Li

[PEFT] LoRA sequence-classification model gives different results after reload: head not in modules_to_save ("Some weights ... were not initialized from the model checkpoint")

Cause (Documented platform behavior): Transformers adds a randomly initialised head; PEFT saves it only when it is in modules_to_save (inferred from task_type for standard names). Fix status: documented_behavior Other error fragments: - You should probably TRAIN this model on a

[Docker Engine API] 'client version X is too old. Minimum supported API version is 1.40' / 'is too new. Maximum supported API version is' — SDK/tool pinned API version

Cause (Documented platform behavior): dockerd rejects API versions outside [minAPIVersion, defaultAPIVersion]. API versions older than defaultMinAPIVersion are deprecated; DOCKER_MIN_API_VERSION on the daemon can lower the minimum (not below 1.24) for exceptional cases. Fix statu

[Instructor] from_provider ConfigurationError: "Model string must be in format \"provider/model-name\"" / "Unsupported provider: azure. Supported providers are: ..."

Cause (Documented platform behavior): from_provider splits on the first "/" and looks the prefix up in its own provider builder table (openai, anthropic, azure_openai, google, gemini, vertexai, bedrock, ollama, litellm, openrouter, ...). Fix status: documented_behavior Other erro
