I tried updating my instance opf ERPNext using bench --update reset

It did not complete succesfully. I got the following output form the console:

I have seen several similar issues on the platform but non of htem solutions worked for me.

Things i have tried:

  • bench --site site1.local set-maintenance-mode off
  • bench restart
  • sudo supervisorctl restart all

Also, could not access the instance anymore on web. Any guide would be appreciated.

Unknown column implies a mismatch of DB structure.
Try

bench update --patch

3

bench update --patch
bench setup requirements
bench update migrate
bench restart

I’ve tried both @trentmu and @Suresh_Thakor suggestions without any success. Still get the same error.

It appears the very command bench update triggers the error.

Also, before attempting the very first bench update that caused the error, I was seeing the same error on the web front-end anytime i try to create a new invoice.

@Suresh_Thakor @trentmu I solved the issues by:

  1. downloading a backup of my database
  2. searching for “reference_dt” in the sql dump. This is because the error message says: “Unknown column ‘reference_dt’ in ‘where clause’”. I saw two instance of the “reference_dt” string in the sql dump. The two instance belong to a single record that was inserted into a “tabCustom Field” table. I guess one of my users must have entered the record.
  3. I removed the record containing the “reference_dt”
  4. I restored the edited version of my sql
    bench --site site1.local --force restore [FILE_PATH]
  5. updated the site
    bench update
  6. Everythng working fine now.
