REPL Completion throws a keymap error - expected MethodCompletion, got TextCompletion

[astrozot]

In a fresh Julia 1.10.8 session, if I type map(a followed by a TAB key (for completion), I get the following error message

julia> map(a┌ Error: Error in the keymap

The same problem appears in version 1.11.3; it was not apparent in 1.10.7 or 1.11.2.

I am running Julia on a Intel MacBook Pro.

[adienes]

I think this is fixed on master

[adienes]

it's #57138

[IanButterworth]

Indeed, and that's marked for backport.
I'll leave this open until it's out on a backport release, as a few of these issues have been opened.

[astrozot]

Thank you for your quick replies. I will wait for the next release and stick to 1.10.7 / 1.11.2 in the meantime.

[sumiya11]

I am getting similar error in 1.11.3

[IanButterworth]

It will be fixed in the next 1.10 and 1.11 releases.

ok. That's a different issue. Please open a new one.
