Bulk Update error latest Manager version

I am using Manager Cloud and experiencing the following error;

  1. After importing bank statement…transactions imported but needs to be categorized;

  2. Clicking on the uncategorized entires brings up the screen - I have bank rules setup, so it automatically assigns accounts. Selecting the ‘Select All’ option and clicking on Bulk Update should assign the transactions;

  3. Clicking bulk update throws up the following error;

Note: following the same process on my own server version: 20.9.84 hosted on ubuntu works well without any issues.

Any ideas to resolve?

Thanks

Should be fixed in the latest version (20.10.17)
