NS_E_CURL_INVALIDURL
What NS_E_CURL_INVALIDURL means at its owning API
When NS_E_CURL_INVALIDURL (0xC00D1329) appears, the first blocked transition is the complete string cannot be parsed into a valid URL structure. In practice, the invalidurl URL check must be reconstructed from the same URL, stream, object generation and call sequence.
Before any socket is opened, the player decomposes a URL into scheme, authority, host, port, path and escaped data at the invalidurl checkpoint. It may also combine a relative reference with a base URL or convert a file URL into a path; each operation has a different validity rule while tracing the invalidurl path. In the case of NS_E_CURL_INVALIDURL, preserve the earliest lower-level result because wrappers can map several different causes to the same HRESULT during a controlled invalidurl retest.
One-component URL experiment
- Log
0xC00D1329,NS_E_CURL_INVALIDURL, the exact operation and the first failure time for evidence about invalidurl. - Preserve the original unmodified string, character count, encoding, base URL if any, parsed scheme, host, port and path, plus required and supplied output-buffer lengths before closing the invalidurl incident.
- Do not reuse a graph, session, reader or metadata object created before the relevant configuration or resource changed in the invalidurl diagnostic record.
- Perform one isolated test: parse the same string into components, correct only the first rejected component, and rerun without changing the resource identity when isolating the invalidurl case.
- Repeat through the same API and protocol path; a different player or local-copy test is useful only as a comparison, not as proof that the invalidurl URL check is fixed.
- Confirm the expected next state and retain any new HRESULT as a separate downstream result while tracing the invalidurl path.
What completed, and what did not
Before the invalidurl URL check, earlier setup may have succeeded, but the complete string cannot be parsed into a valid URL structure was not completed. This is why logs should preserve both the last successful call and NS_E_CURL_INVALIDURL.
The targeted comparison is parse the same string into components, correct only the first rejected component, and rerun without changing the resource identity before closing the invalidurl incident. It changes the disputed precondition without changing the media identity or unrelated machine settings in the invalidurl diagnostic record.
Preserve the raw and parsed URL
| Capture | Why it separates NS_E_CURL_INVALIDURL |
|---|---|
| Owning call | Record the API method, object identity, thread or callback and timestamp for the invalidurl URL check. |
| Decisive values | the original unmodified string, character count, encoding, base URL if any, parsed scheme, host, port and path, plus required and supplied output-buffer lengths at the invalidurl checkpoint. |
| Object generation | Note when the reader, writer, graph, URL object, streaming session or metadata provider was created; stale state can reproduce NS_E_CURL_INVALIDURL after configuration has changed. |
| First nested result | Keep the earliest codec, COM, socket, DNS, parser or provider status before NS_E_CURL_INVALIDURL; later UI messages are less specific. |
| Comparison case | Use one known-good resource that exercises the same the invalidurl URL check while changing only the rejected precondition. |
What the parser result proves
| Retest result | Interpretation for NS_E_CURL_INVALIDURL |
|---|---|
| The identical call still returns the code | The values governing the invalidurl URL check are unchanged, or the caller is still using an older object generation. |
| A fresh object succeeds | Lifetime or cached state contributed to NS_E_CURL_INVALIDURL; correct object recreation instead of applying a machine-wide workaround in the invalidurl diagnostic record. |
| The call advances to another HRESULT | The the invalidurl URL check boundary was cleared. Diagnose the new code at its own format, graph, URL, network or metadata stage at the invalidurl checkpoint. |
| Only one resource fails | The evidence favors content, URL, publishing point, stream, attribute or object-specific state rather than a global outage while tracing the invalidurl path. |
Misleading actions
- blindly decoding and re-encoding the whole URL, which can change reserved delimiters and resource identity during a controlled invalidurl retest.
- Do not erase the first
NS_E_CURL_INVALIDURLoccurrence by repeatedly retrying; callbacks and reconnects can replace the useful state with a later wrapper error for evidence about invalidurl. - Do not publish credentials, protected-content material or complete private URLs before closing the invalidurl incident. Record redacted identifiers, lengths, hashes and protocol fields needed to reproduce the invalidurl URL check.
Nearby results are not interchangeable
Main distinction: URL syntax errors occur before server DNS, proxy selection or streaming-session creation when isolating the invalidurl case.
| Nearby HRESULT | How to compare it |
|---|---|
NS_E_CURL_INVALIDPATH | Compare the owning API and first rejected value; it belongs to a neighboring checkpoint, not automatically to the same cause as NS_E_CURL_INVALIDURL. |
NS_E_CURL_INVALIDSCHEME | Use object state and operation order to decide which code is authoritative when both appear in one trace while tracing the invalidurl path. |
NS_E_CURL_CANTWALK | Retain this result separately if it appears only after the NS_E_CURL_INVALIDURL condition has cleared. |

For NS_E_CURL_INVALIDURL, retain the post-fix trace so a later pipeline result is not mistaken for recurrence of this boundary for evidence about invalidurl.
