If problems occur in the DRACOON Web App, they can usually be logged using the developer tools built into each browser (for PC and Mac). The communication between the DRACOON Web App and the relevant DRACOON environment (in the DRACOON cloud) is recorded in the browser—both the requests of the Web App and the responses of the DRACOON environment. The recorded log can then be saved as a so-called HAR log file on the computer and finally forwarded to DRACOON Support for analysis of the problem.
If DRACOON Support asks you to log and submit a problem occurring in the DRACOON Web App in a HAR file, proceed as follows:
- Open the DRACOON Web App and go to the location where the problem occurs.
- In Chrome, click the three-dot menu in the upper-right corner, point to More tools on the menu, and click Developer tools on the submenu.
Alternatively, you can press F12 to open the developer tools.
- Click the Network tab:
If the Network tab is not visible because the display area is too narrow for the developer tools, click the double arrow , and then click Network on the menu.
- Make sure that the logging settings are active: The record button should be red (if not: click it—it should then be displayed in red), and the Preserve log check box must be selected.
- Click the button ("Clear") to ensure the log is empty.
- Reproduce the problem in the DRACOON Web App. After the problem has occurred, immediately stop recording in the developer tools by clicking the red button so that it is grayed out (this prevents the recording of subsequent events that are not related to the problem).
- Click the button ("Export HAR"):
- Select the folder where you want to save the HAR log file, and if necessary, change the file name suggested by Chrome for the HAR file.
- Close the Chrome developer tools by clicking the X button in the upper-right corner of the developer tools or by pressing F12.
- If you were signing in to the DRACOON Web App while logging was already in progress, the HAR file contains the user's login password twice in plain text (unless the login was via OpenID Connect)—the password should therefore be removed from the HAR file before it is forwarded to DRACOON Support! To remove the password from the HAR file, open it with an editor and use it to search for path=login in the file. Delete the password that is contained in the line found. 12 lines below that, the password can be found again in a separate line—also remove this occurrence from the HAR file and save the changes.
Example (the two password occurrences to be deleted are marked here):
- Send the saved HAR log file to DRACOON Support for problem analysis (as an attachment in the ticket form, for example).
- Open the DRACOON Web App and go to the location where the problem occurs.
- In Edge, click the three-dot menu in the upper-right corner, point to More tools on the menu, and click Developer tools on the submenu.
Alternatively, you can press F12 to open the developer tools. You may then have to click the Open DevTools button in the message that appears.
- Click the Network tab:
If the Network tab is not visible because the display area is too narrow for the developer tools, click the double arrow , and then click Network on the menu.
- Make sure that the logging settings are active: The record button
should be red (if not: click it—it should then be displayed in red), and the Preserve log check box must be selected. - Click the button ("Clear") to ensure the log is empty.
- Reproduce the problem in the DRACOON Web App. After the problem has occurred, immediately stop recording in the developer tools by clicking the red button so that it is displayed in black
(this prevents the recording of subsequent events that are not related to the problem). - Click the button ("Export HAR"):
If you can't see the ("Export HAR") button, the display area is too narrow for the developer tools. Then, move the dividing line between the webpage viewport and the developer tools pane to make the developer tools wider.
- Select the folder where you want to save the HAR log file, and if necessary, change the file name suggested by Edge for the HAR file.
- Close the Edge developer tools by clicking the X button in the upper-right corner of the developer tools or by pressing F12.

- In Firefox, click ☰ in the upper-right corner, click More tools on the menu, and then click Web Developer Tools on the submenu.
Alternatively, you can press F12 to open the web developer tools.
- Click the Network tab:
If the Network tab is not visible because the display area is too narrow for the developer tools, click the double arrow , and then click Network on the menu.
- Click the trashcan button ("Clear") to ensure the log is empty.
- Reproduce the problem in the DRACOON Web App. After the problem has occurred, immediately stop recording in the developer tools by clicking the pause button || (this prevents the recording of subsequent events that are not related to the problem).
- Click the cog button ("Network Settings"), and in the menu that appears, click Save All As HAR:
- Select the folder where you want to save the HAR log file, and if necessary, change the file name suggested by Firefox for the HAR file.
- Close the Firefox developer tools by clicking the X button in the upper-right corner of the developer tools or by pressing F12.
