Mailpit UI has the same issue

[cescoffier]

If you use the web inspector, do you see any JavaScript error in the console?

[danieloh30]

I found this error in the debug mode

[cescoffier]

Thanks @danieloh30, let's wait for @phillip-kruger.

@danieloh30 happy that someone is using Mailpit! Thanks for reporting this issue.

[danieloh30]

@melloware I love it. I usually use the MailPit for my live demo when I code a tool + RAG :)

[phillip-kruger]

@danieloh30 thanks for the catch. There is a PR to fix this now and I marked it to backport so it should be in the next patch release.

[danieloh30]

Sounds good! Hope the PR will fix the swagger-ui too.

When do you expect to release the next version? I have a live demo next week at Devoxx UK. @phillip-kruger

[phillip-kruger]

What do you mean fix the swagger-ui ? What was broken there ? I an not sure when the next release is, maybe @gsmet can help ?

[danieloh30]

Yeah, when I access the swagger-ui from Dev UI, it's an empty page like Mailpit and REST endpoint.

[phillip-kruger]

Ok yes that should be fixed. Basically any non-router (spa of the dev ui) would have been broken

[danieloh30]

Sounds good!
