Every route of a SmoothAgentApi deploy fails with:

Error: Runtime not found: provided.al2023

The bug

args.handler is a prebuilt artifact directory — the cargo lambda output holding bootstrap. Passing it as handler makes SST try to build it, and SST dispatches its builder on the runtime string.

There is no builder registered for the literal provided.al2023. SST expects rust or go as the build input and maps those to that Lambda runtime itself:

runtime.apply((v)=>(v==='go'||v==='rust' ? 'provided.al2023' : v))

So provided.al2023 is a valid Lambda runtime and an invalid SST build runtime — easy to conflate, and the arg is named runtime for both.

The fix

bundle is SST's documented way to say "I built this myself, skip bundling", with handler naming the entrypoint inside it:

bundle: args.handler,// prebuilt cargo-lambda output dirhandler: 'bootstrap',// the binary inside itruntime: 'provided.al2023',

Why it was slow to spot

It failed at the wrong-looking layer. Each route successfully created its CloudWatch log group and IAM role first, so the run read as a permissions problem right up until the build step — and the deploy had genuinely hit four real IAM denials before this one, which made a fifth entirely plausible.

Provenance

Found deploying smooth-operator's serverless flavor for the first time (SmooAI/smooth-operator#559). That path had never actually been run end to end, which is also how it shipped with a wrong ARTIFACT_DIR and a config that sst install rejected outright.

Verification

Typecheck is unchanged: 93 pre-existing errors on main (the sst ambient globals a library checkout can't resolve), 93 with this change — verified by stashing and re-running, not assumed.

Every route of a SmoothAgentApi deploy fails with:

Error: Runtime not found: provided.al2023

The bug

args.handler is a prebuilt artifact directory — the cargo lambda output holding bootstrap. Passing it as handler makes SST try to build it, and SST dispatches its builder on the runtime string.

There is no builder registered for the literal provided.al2023. SST expects rust or go as the build input and maps those to that Lambda runtime itself:

runtime.apply((v)=>(v==='go'||v==='rust' ? 'provided.al2023' : v))

So provided.al2023 is a valid Lambda runtime and an invalid SST build runtime — easy to conflate, and the arg is named runtime for both.

The fix

bundle is SST's documented way to say "I built this myself, skip bundling", with handler naming the entrypoint inside it:

bundle: args.handler,// prebuilt cargo-lambda output dirhandler: 'bootstrap',// the binary inside itruntime: 'provided.al2023',

Why it was slow to spot

It failed at the wrong-looking layer. Each route successfully created its CloudWatch log group and IAM role first, so the run read as a permissions problem right up until the build step — and the deploy had genuinely hit four real IAM denials before this one, which made a fifth entirely plausible.

Provenance

Found deploying smooth-operator's serverless flavor for the first time (SmooAI/smooth-operator#559). That path had never actually been run end to end, which is also how it shipped with a wrong ARTIFACT_DIR and a config that sst install rejected outright.

Verification

Typecheck is unchanged: 93 pre-existing errors on main (the sst ambient globals a library checkout can't resolve), 93 with this change — verified by stashing and re-running, not assumed.
