Have you tried to run in debug mode to check which variable is null on that line?

:wink: i actually had not done that. i was using my eyes to check :sunglasses:

4

but it compiles fine, and loads fine . …the problem comes wen i click the link. but let me try he debugg mode

5

hi @dkayiwa after running the sdk server in debug mode… using mvn openmrs-sdk:run -Dfork=false -Ddebug

here s the log. https://pastebin.com/sTG5qYtg

Does it run well if you do not run in debug mode?

8

@dkayiwa i think i havent got the question …

9

You are running the sdk in debug module. Do you still get this error if you run the sdk again but not in debug mode?

10

@dkayiwa here this is the log without the debug mode https://pastebin.com/rgMBt9D0

11

Does it help if you delete the contents of this folder? C:\Users\Dell.m2\repository

12

yes , i delted it , and ran the sdk again , i got a cleaner log wth few errors, but i still the java.lang.null.pointerException

13

i have seen the variable that is not instatiated

14

this is the other error i have now

This looks like a messed up database. It could be easier to just set it up afresh.
