No plotly graph in Computers tab

[megachester]

Why might such a problem appear?
Tasks can be run.

It happens both in minimal and full modes

@megachester , Looks like an internal error.

The program has last activity = null for that computer.

Could you please provide me with the log file?

cat ~/mlcomp/logs/log.txt

@megachester , how have you installed the library? Via Pypi or from the Github sources?

Please try version 20.2.4. I have uploaded it just now.

For example:

# stop server and workers
pip install -U mlcomp
mlcomp migrate
# start server and workers

Does it help?

[megachester]

No, it didn't help

[lightforever]

There is the version 20.2.4b.

Please update mlcomp to it.

Then:

1. mlcomp report
   This command will create a report. Please attach it to the issue. (I hope your logs do not contain secure information).

2. Please open the Console in your browser. Are there errors?

[megachester]

1. Is it better to clear everything and execute report after fresh mlcomp init procedure?

2. What do you mean by Console?

[lightforever]

1. Yeah, it would be better

2. https://kb.mailster.co/how-can-i-open-the-browsers-console/

   https://web.dev/errors-in-console/

[megachester]

1. report1203.zip

2. You were right, there are errors of such type:
   Error: InvalidPipeArgument: 'Unable to convert "2020-03-12 12:45:17Z" into a date' for pipe 'DatePipe'

Sorry, but I have no idea why it happens.

You could debug the issue: open tables computers and docker in your database and check them on null values.

Also, try to open the page in a different browser. For example, I use Google Chrome.

[megachester]

Thanks! Opening front in Chrome helped. The problem is with Safari.
