Feature Request: Allow queued voluntary exits

[hentai8]

Describe the bug

./validator accounts voluntary-exit --holesky --beacon-rpc-provider=xxxx --validators-external-signer-url=xxx --validators-external-signer-public-keys=0xxxx --public-keys=0xxxx --accept-terms-of-use --force-exit

I'm having the expected current epoch >= exit epoch problem when I run this command, this is an occasional occurrence and the probability of it happening is not high, I use this command a lot due to my development needs, I've encountered this problem maybe 2 times in the past year of development and when it occurs, it stays with this error for 1 Even if I re-execute the command, it still has the error, and the problem does not return to normal until the next epoch.

For this reason I read the relevant part of the code and found the error in this location, I think it is signed the wrong epoch, the exact cause of the error I don't know yet, but I would like to report this, I would be very grateful if you could locate this problem and fix it, because I use this code a lot.

Has this worked before in a previous version?

I've had this bug since v4.x. I'm currently running v5.0.3 and still have this bug.

What version of Prysm are you running? (Which release)

v5.0.3

Anything else relevant (validator index / public key)?

No response

hmm are you sure you are not just requesting it on an account too early? you are exiting before the node thinks it's on the exit epoch

[hentai8]

I just executed the command I mentioned above, and the logic should have been implemented internally by prysm, so I think it's an internal bug

[james-prysm]

We don't have queueing your request as a feature in prysm, you're probably just executing the command too early, you need to wait till the beacon chain is at or after the epoch to run the exit

Updated the title to reflect that a possible resolution to this issue would be to add some kind of pool to the beacon node to hold local voluntary exits and only publish them when they become valid.

Thank you very much for your attention to my question.
