LinkvalidationError when bench update

When i do bench update, I get an error.

frappe.exceptions.LinkValidationError: Could not find Text Color: #000000, Background Color: FFFFFF

I have even tried removing me entire erpnext/frappe installation en restoring everything back, but it remains the same.

It may help to say the operating environment, the version of ERPNext and if this is happening on a new installation or one that had been upgrading ok .

Has bench update --reset been tried?

My environment :

  • Ubuntu 18.04.5 LTS
  • Removed erpnext, installed with the install script, and restored the database
  • It worked before I restored the database
  • bench update --reset gives me the same error

Why are you restoring the backup?

I had this problem and couldn’t get it fixed.
So in an attempt to resolve this, I removed my erpnext installation and installed everything from cratch.
Then I restore my data, and the problem came back.

To fix this I updated the values in ‘tabWebsite Theme’ and set the values for ‘background_color’ and ‘text_color’ to null.
This got me past the bench update without error.
