When trying to update a custom task's version I get this error:
Task definition visible rule 'serviceType = A || serviceType = B || ((serviceType = C || serviceType = D) && deploymentMode = Docker)' is invalid. It should be of format "A <validconditionhere> B"
What is the correct syntax for the visible rule to make the equivalent condition above?
From looking at task samples,I am afraid that you can not use ( ...).It looks like expression conditions are somewhat limited.
I suggest to try the following based on these samples to avoid using () and see if this work for you.
"visibleRule": "serviceType = A || serviceType = B || serviceType = C && deploymentMode = Docker || serviceType = D && deploymentMode = Docker"
