/**
|

|
|
* LangSmithConflictError
|
||
|
|
*
|
||
|
|
* Represents an error that occurs when there's a conflict during an operation,
|
||
|
|
* typically corresponding to HTTP 409 status code responses.
|
||
|
|
*
|
||
|
|
* This error is thrown when an attempt to create or modify a resource conflicts
|
||
|
|
* with the current state of the resource on the server. Common scenarios include:
|
||
|
|
* - Attempting to create a resource that already exists
|
||
|
|
* - Trying to update a resource that has been modified by another process
|
||
|
|
* - Violating a uniqueness constraint in the data
|
||
|
|
*
|
||
|
|
* @extends Error
|
||
|
|
*
|
||
|
|
* @example
|
||
|
|
* try {
|
||
|
|
* await createProject("existingProject");
|
||
|
|
* } catch (error) {
|
||
|
|
* if (error instanceof ConflictError) {
|
||
|
|
* console.log("A conflict occurred:", error.message);
|
||
|
|
* // Handle the conflict, e.g., by suggesting a different project name
|
||
|
|
* } else {
|
||
|
|
* // Handle other types of errors
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @property {string} name - Always set to 'ConflictError' for easy identification
|
||
|
|
* @property {string} message - Detailed error message including server response
|
||
|
|
*
|
||
|
|
* @see https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/409
