BUG - deletion of links through web-ui (server-related)

[miromeir]

This was only tested in the web-ui, it throws an error upon deleting a link.
The reason is CORS related, probably the preflight checks of the DELETE request is being blocked.
The solution was to add

allow_methods="*"

to the cors ResourceOptions in web_server.py
Can you please check if this bug is reproducible?
if so, i'd love to submit a pull request, perhaps discuss an alternative solution.

I am a bit confused because allow_methods is already set with "*": https://github.com/GNS3/gns3-server/blob/3.0/gns3server/api/server.py#L70

[miromeir]

now I am a bit confused as well.
The code i'm referring to is on branch "master", and it uses aiohttp for the api.
Your link points to a v3.0, that has FastAPI instead.
is master not the correct branch to clone from?

[grossmj]

Sorry, I thought you were talking about v3.0.

For v2, I think you must have changed this code:

https://github.com/GNS3/gns3-server/blob/master/gns3server%2Fweb%2Fweb_server.py#L314-L325

Is this correct?

[miromeir]

That's correct.
