Dynamic Content Delivery Network:Common ER errors

Error message

@Fetch.fetch: fetch authority is same with origin authority, which is forbidden

Cause

You cannot initiate a fetch request to the domain name of a routine in the code of the routine. For example, if the domain name of a routine is 1.a.com, you can initiate a fetch request to a domain name other than 1.a.com in the code of the routine.

Error message

HttpBody.constructor: invalid status code

Cause

596, 597, 598, and 599 are response status codes used in EdgeRoutine (ER). You cannot use these status codes in your code.

Error message

io error@: io error(Connection reset by peer)

Cause

If the execution time of a routine exceeds the CPU time slice specification, the routine ends the connection. The virtual machine (VM) that runs the routine is stopped, and an error log is generated.

Solution

Increase the CPU time slice specification, such as, from 50 ms to 100 ms.

Error message

unhandled error(13485,13477)@: Error: io error@: no available fetch proxy address now\nstacktrace:\nN/A\n

Cause 1

The URL in the cache.put method starts with https. The cache API does not support https. Therefore, you need to change https to http.

Cause 2

You sent a fetch request to a domain name that is not added to Alibaba Cloud CDN, and you have added the cdnProxy:true configuration. In this case, you need to add the domain name to Alibaba Cloud CDN or Dynamic Content Delivery Network (DCDN), or delete the cdnProxy:true configuration.

Error message

Error: unhandled error(13486,13505)@: Broken connection, unexpected EOF

Cause

When a routine receives the data returned from the upstream service, the upstream service ends the connection.
