it may conflict with one of the packages (but not sure) ...!

[hazho]

now I convert the project to python3.8, but the issue is same

[RNCTX]

Had the same issue, found the fix in a fork....

diurnate@84da669

Could either of you provide more context for replicating the issue?

[RentFreeMedia]

There are some scenarios that I don't fully understand where request is not in block context. If I remember correctly, the fix was the superclass having request (always) so grabbing it if it doesn't exist in the present block context.

@alxbridge you seem to be the main person maintaining the library at the moment. Would a PR for the changes in diurnate@84da669 be welcome, or is there another way recommended for unit testing blocks that use PersonalizedStructBlock? Happy to help contribute in whatever way makes the most sense.
