OptionalcontentLengthHeader: numberThe parsed value of the Content-Length response header when the cap
was tripped on the pre-check (before any body bytes were read). Undefined
when the response was streamed and exceeded the cap mid-flight, or when
the server omitted the header.

StaticstackThe Error.stackTraceLimit property specifies the number of stack frames
collected by a stack trace (whether generated by new Error().stack or
Error.captureStackTrace(obj)).
The default value is 10 but may be set to any valid JavaScript number. Changes
will affect any stack trace captured after the value has been changed.
If set to a non-number value, or set to a negative number, stack traces will not capture any frames.
OptionalcauseOptionalstackStaticcaptureCreates a .stack property on targetObject, which when accessed returns
a string representing the location in the code at which
Error.captureStackTrace() was called.
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack; // Similar to `new Error().stack`
The first line of the trace will be prefixed with
${myObject.name}: ${myObject.message}.
The optional constructorOpt argument accepts a function. If given, all frames
above constructorOpt, including constructorOpt, will be omitted from the
generated stack trace.
The constructorOpt argument is useful for hiding implementation
details of error generation from the user. For instance:
function a() {
b();
}
function b() {
c();
}
function c() {
// Create an error without stack trace to avoid calculating the stack trace twice.
const { stackTraceLimit } = Error;
Error.stackTraceLimit = 0;
const error = new Error();
Error.stackTraceLimit = stackTraceLimit;
// Capture the stack trace above function b
Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
throw error;
}
a();
OptionalconstructorOpt: FunctionStaticprepare
Error thrown when a response body exceeds the configured
maxResponseBytescap on the transport. Surfaced when crawling untrusted agents (registries, federated discovery layers) to prevent a hostile vendor from buffering a large reply before schema validation runs.Recovery:
terminalfrom the SDK's view — repeating the call against the same agent will hit the same cap. The buyer's options are to widen the cap (per-calltransport.maxResponseBytes) when the agent's payload is legitimately large, or to flag the agent as misbehaving.
