is that why all my pilots are (cached) with a 404 not found error on esi?

EVEMon 4.0.20.4986

I think yes. The /v4/ route returns the 404 (deprecated probably).

Came here to report the same thing. Characters started going (cached) for me yesterday, and this corresponds to when they deprecated the endpoint as I had to update my pathfinder install as well.

This worked perfectly, thanks

How can we implement this fix?

Just search the solution for the text

<value>/v4/characters/{0:D}/</value>

and replace it by

<value>/v5/characters/{0:D}/</value>

And recompile evemon.

Is there a .21 version in the offing?

I'm selfishly hoping that there's an update available that I don't have to try to do myself.

Ehm... can anyone please publish a fix? I'm afraid I'm unable to compile... :(

Many thanks!

I forked the repo and followed the the OP to make a fix. Took a little wrestling to get it to build correctly, but after reading the docs on the old wiki for how to setup VS Code, and moving to a path without a space in it, I was able to get it to build.

My fork: 4.0.20.1-esi-v5-characters.

Use at your own risk, obviously. The only changes I've made were to fix the ESI path and update the version string. If you're concerned you should be able to build it pretty easily yourself. The installer will be found in src\EVEMon\bin\Installbuilder\Installer after you build the project.

Did you also update the static data?

New fork seems to be working, many thanks!

Did you also update the static data?

I did not. I would be happy to do so if I knew how.

If you have applied the improvements i made it's a matter of running the tools\XmlGenerator project
You might have to delete the sqlite-latest.* files (if present) before running to force the tool to redownload of the latest version.
It will save files into the evemon project and your %appdata%\evemon folder (where the Evemon installer puts them too). So running the installer afterwards should include the new zipped static data.

FYI @ajaxify there are several places this endpoint needs updated, not just the ESICharacterSheet:

@wvdvegt I'm trying to update the static data and could use some help if you've gotten it working before: I've built the project and run the exe and it's throwing a SQL error no such table: agtAgents:

I end up with a 0 byte sqlite-latest.sqlite file. I'm not a C# developer (just Python) so I'm not sure what the deal is here. It is expecting that the file already exists and is populated with data already? Do I actually need to have MSSQL Server installed and import the CCP static data dump first for this to work (like described here)?

The .sqlite is just the uncompressed sqlite-latest.sqlite.bz2 (you could try to manually decompress it with a tool as winrar). The unzip takes quite some time btw.

To force a re-download from fuzzworks you have to delete the two sqlite-latest version before the xml tool is started.

If the .sqlite file is 0 bytes in size, the file is corrupt and tables do not exists. So the error message fits the .sqlite file size.

There's no sqlite-latest.sqlite in the repo before I run the tool. I ran the tool, which then threw the errors at which point I end up with the 0 byte sqlite file.

It's the sqlite-latest.sqlite.bz2 you have to delete too (that is the zipped archive containing sqlite-latest.sqlite)

I just checked my XmlGenerator project and it downloaded, unzipped & generated the files just fine.

The bz2 file is located at https://www.fuzzwork.co.uk/dump/sqlite-latest.sqlite.bz2

It's correct there is no sqlite file in the project before running the tool as the tool downloads and unzips the bz2 archive. (this was a manual operation in the original version).

It's weird. I don't have any sqlite-latest.sqlite.bz2 or sqlite-latest.sqlite before running the tool. It's like it's not downloading/unzipping the file from fuzzwork.

Then i think you have the version without my patch. You will need to manually download and unzip the bz2 file from fuzzworks then.

Ah, my bad. I didn't know you had a patch somewhere for the XmlGenerator. I'm just working off the main branch on this repo.

OK, that worked fine. Data files are updated and I rebuilt the installer so everything is sweet now. In case someone wants a version with all the v4 endpoints fixed and the latest static data, here's an installer:

https://github.com/dephekt/evemon/releases/tag/v4.0.20-dephekt

If you want to keep the latest static data, you need to ignore the "Data Update Available" notification as it will download the old data from the March 2021 release if you choose to update.

FYI @ajaxify there are several places this endpoint needs updated, not just the ESICharacterSheet:

I'm not sure this is accurate. Only the character sheet was updated to v5, the rest (skills, clones, etc) are still v4 according to the ESI reference page?

https://esi.evetech.net/ui/#/Skills/get_characters_character_id_skills

I only updated the character sheet version in my copy and it works just fine

Thanks for the info on the XMLGenerator, I was also running into the same problem but hadn't had a chance to ask for help here yet. I will try to reproduce and update my fork as well.

@wvdvegt would you mind linking to the patch you're talking about? Thanks!

See #294 for the patch.

Yeah, you're right. The first read of the forum post and the issue CCP made about this I understood it as anything under /v4/characters/{id} and saw references elsewhere to /v5/characters/{id}/clones for example. If you tested the other functionality still using the /v4/characters route and things still worked then I guess this isn't necessary.

In fact, later I did this on my own copy and at first noticed no issues. Then after adding a few new characters I saw weird behavior, like some skills in the character sheet not showing up (but others do), which is probably related to changing these other URLs to v5. I never looked into the raw response data to see what is actually going on though.

Sorry for the confusion.

According to https://github.com/esi/esi-issues/blob/master/changelog.md then the change was

REMOVAL /v4/characters/{character_id} (legacy)
    The only difference between v4 and v5 is the fact that v4 contains as an optional field ancestry_id.

It was scheduled and postponed multiple times but eventually the removal was deployed on 2021-10-25.

Is there a plan to get EVEMon correspondingly fixed and the clients in the field updated?

There is a need to get these older clients updated:

• EVEMon/4.0.17.4966
• EVEMon/4.0.18.4979
• EVEMon/4.0.19.4983
• EVEMon/4.0.20.4986
