Expand description

When a syscall fails, it returns an ErrorNumber to indicate why. The syscalls themselves include documentation on which syscall errors they can be expected to return, and what they mean in the context of the syscall.

Variants

IllegalArgument

A syscall parameters was invalid.

IllegalOperation

The actor is not in the correct state to perform the requested operation.

LimitExceeded

This syscall would exceed some system limit (memory, lookback, call depth, etc.).

AssertionFailed

A system-level assertion has failed.

Note

Non-system actors should never receive this error number. A system-level assertion will cause the entire message to fail.

InsufficientFunds

There were insufficient funds to complete the requested operation.

NotFound

A resource was not found.

InvalidHandle

The specified IPLD block handle was invalid.

IllegalCid

The requested CID shape (multihash codec, multihash length) isn’t supported.

IllegalCodec

The requested IPLD codec isn’t supported.

Serialization

The IPLD block did not match the specified IPLD codec.

Forbidden

The operation is forbidden.
