ERD Tool: Save Image: does not save anything...

[pms967]

Describe the bug

The title say it all: with a project imported (or loaded) into the ERD Tool, I've tried to save the ERD scheme as an image (too: saving as .pgerd and .sql file seems to work fine) .

After clicking on the icon (or pressing the shortcut), the screen greys out with the message: “Preparing the image”. Then after a while it goes back to normal, and that's it.

Unfortunately, nothing else happen. No file selector to choose folder and file name appears, and apparently no image file has been created anywhere.

That must be some kind of regression: several months ago, on the same system and with (almost) the same DB, an earlier version did work just fine.

Error message

None. I found these in the log, but I am not sure whether they are related / relevant:

Hi @pms967,

Before saving the image - Go to View -> Toggle Developer Tools -> Console and then try to save image. Share the errors if any from the console.

Here it is:

pgadmin4.log

N.B.: these messages appears as soon as I open the ERD Tool:

BTW: worse yet, while I was able to open an older project (actually, an older version of the same one, saved some times ago) , now it can not even open a .pgerd which I have saved yesterday.

As soon as I try to open that file, pgAdmin4 freezes and I have to manually kill the processes. In that case, no new message whatsoever appears on the console.

There is a similar freezing related bug open for ERD - #8389. May be related to that.
Need to check console error of 404. I don't get such error on my installed pgAdmin.

May be related to that. Need to check console error of 404. I don't get such error on my installed pgAdmin.

Could be some missing library which is not listed as dependency in the .deb package?

Or maybe some other misconfiguration and/or missing file in the package?

In that case, pgAdmin itself won't have opened.

Hi @pms967,

I am not able to reproduce the issue. Can you please provide the pgerd file?

It looks like it happens to me with any project. Anyway, here's one example.
