[Keno]

Same issue here - I interrupted Claude during a Web Search, so that may be what caused it

[SamuelSchlesinger]

Yep, this continually happens with the Web Search tool in particular.

[SamuelSchlesinger]

It's happened to me a bunch of times.

[Kanezal]

same error but in think mode

[SamuelSchlesinger]

I'd really appreciate the option to either get rid of the tool call that caused this or to add an arbitrary response I write myself, or to retry the tool call. Anything but bricking the session
