can't run and add cell

[CaiYitao]

0.12.3 is not stable, sometimes it can't run and add cell or even send out feedback! close it and reopen can solve it, but it happens again sometimes.

[fonsp]

I'm sorry to hear that, could you give some more info?

• What browser do you use? What version?

• What do you reopen to solve it? The browser or the Pluto server?

• Maybe you could describe the issue in more detail. What does it look like when you can't run a cell? Are there other things that still work?

[CaiYitao]

Hi Fons, Thanks for your reply, normally I use safari cause it is default one, newest version. sometimes use chrome. I closed both notebook and server, and reopen them again to solved it. when I click the plus sign to add or press shift+return button to run a cell, it does not react at all. Btw,I love Pluto, it is an exceptional product, great job! When can we export reactive content as video? Kind regards Yitao Cai

Thanks! Could you try to narrow it down?

• On which of the two browsers does the problem occur?

• Does it happen on every notebook, or a specific one?

• Is the window completely frozen? Can you still type text?

But most importantly:

It would be really helpful if you could share the output of the browser developer console after it crashes:

Press Command+Option+J to open the console. For me it looks like this:

Take a screenshot and send it to us.

Similarly, the output of the terminal where you launched Pluto would be very helpful. It looks like this:

Hi Fons, The error was in Safari. and until now it does not happen again, I thought it probably is a problem of my computer.&nbsp; the window wasn't frozen,I can type words. I just run into some new error which is attached here. and in Julia REPL there are error messages as following when I opened homework3.jl from MIT computational thinking course. ┌ Warning: Reading WebSocket client stream failed for unknown reason: │ &nbsp; exception = │&nbsp; &nbsp; IOError: read: connection reset by peer (ECONNRESET) │&nbsp; &nbsp; Stacktrace: │ &nbsp; &nbsp; [1] wait_readnb(::Sockets.TCPSocket, ::Int64) at ./stream.jl:350 │ &nbsp; &nbsp; [2] eof at ./stream.jl:48 [inlined] │ &nbsp; &nbsp; [3] eof(::HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}) at /Users/mindy/.julia/packages/HTTP/IAI92/src/ConnectionPool.jl:199 │ &nbsp; &nbsp; [4] eof at /Users/mindy/.julia/packages/HTTP/IAI92/src/WebSockets.jl:251 [inlined] │ &nbsp; &nbsp; [5] (::Pluto.var"#208#215"{Pluto.ServerSession,Base.RefValue{Function}})(::HTTP.WebSockets.WebSocket{HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}}) at /Users/mindy/.julia/packages/Pluto/R8t0Y/src/webserver/WebServer.jl:139 │ &nbsp; &nbsp; [6] upgrade(::Pluto.var"#208#215"{Pluto.ServerSession,Base.RefValue{Function}}, ::HTTP.Streams.Stream{HTTP.Messages.Request,HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}}; binary::Bool) at /Users/mindy/.julia/packages/HTTP/IAI92/src/WebSockets.jl:160 │ &nbsp; &nbsp; [7] upgrade at /Users/mindy/.julia/packages/HTTP/IAI92/src/WebSockets.jl:142 [inlined] │ &nbsp; &nbsp; [8] (::Pluto.var"#207#214"{Pluto.ServerSession,HTTP.Handlers.Router{Symbol("##253")},Base.RefValue{Function}})(::HTTP.Streams.Stream{HTTP.Messages.Request,HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}}) at /Users/mindy/.julia/packages/Pluto/R8t0Y/src/webserver/WebServer.jl:134 │ &nbsp; &nbsp; [9] handle at /Users/mindy/.julia/packages/HTTP/IAI92/src/Handlers.jl:269 [inlined] │ &nbsp; &nbsp; [10] #4 at /Users/mindy/.julia/packages/HTTP/IAI92/src/Handlers.jl:345 [inlined] │ &nbsp; &nbsp; [11] macro expansion at /Users/mindy/.julia/packages/HTTP/IAI92/src/Servers.jl:367 [inlined] │ &nbsp; &nbsp; [12] (::HTTP.Servers.var"#13#14"{HTTP.Handlers.var"#4#5"{HTTP.Handlers.StreamHandlerFunction{Pluto.var"#207#214"{Pluto.ServerSession,HTTP.Handlers.Router{Symbol("##253")},Base.RefValue{Function}}}},HTTP.ConnectionPool.Transaction{Sockets.TCPSocket},HTTP.Streams.Stream{HTTP.Messages.Request,HTTP.ConnectionPool.Transaction{Sockets.TCPSocket}}})() at ./task.jl:356 └ @ Pluto ~/.julia/packages/Pluto/R8t0Y/src/webserver/WebServer.jl:180 ┌ Error: Download failed: curl: (7) Failed to connect to ia800303.us.archive.org port 443: Connection refused └ @ Base download.jl:43

Thanks! It looks like you sent the screenshot using an email, but you need to visit github.com to send images. Can you try that?

[CaiYitao]

I can open it in chrome by copying the link listed in REPL when run Pluto.run().
I used to open it in chrome by typing localhost:1234. but it is ok for me.

[fonsp]

I need to see a screenshot of the error that you talked about: #553 (comment)

[CaiYitao]

It does not happen again, it might be a problem of my computer yesterday.
