What version are ERPNext and Frappe on ?

[Anjan_Dev]

hi @centaur ,
i tried bench version and it is also giving me errors . i will put the screenshot below.frappe version is 5.8.1

[centaur]

Hmm

If you are on the develop branch the minimum required version of python has been upped to 3.10

Dropping python <=3.9 support for next version of Frappe/ERPNext

This is just a heads-up that we have dropped support for python versions up to 3.7 for the next release. After further thought and discussion, support for 3.8 and 3.9 is also dropped for the next version. [image] 3.10 is the recommended and required version for next/development version of Frappe/ERPNext. If you’re on version-13 this doesn’t affect you yet. If you’re an app developer, you probably need to bump the python version to 3.10 or higher in any automated test suites you’re running. …

There was breaking changes here

fix(doc)!: Always cast datetime, date and time fields (#15891)

and a revert here as well

Revert "fix(doc)!: Always cast datetime, date and time fields"

If you are on develop you could do a bench update --reset and try

[Anjan_Dev]

bench update --reset also gives the same error @centaur
