Prevent squashed commits in master branch

[Julián Lastiri]

Hello,

I have a repository where I have two merge strategies enabled (Merge commits, squashed)

I want to prevent squashed commits in the master branch but I want to allow merge/squashed commits in all other branches.

I came across the following thread (https://community.atlassian.com/t5/Bitbucket-questions/Enforce-a-merge-strategy-per-branch-using-a-merge-hook/qaq-p/1968218) which describes the same problem but the solution is implemented with hooks and I would like to to see if there is an option to implement it  with Bitbucket ScriptRunner conditional merge check.

Is it possible to fetch the merge strategy through MergeRequest.getContext ? How?
If not, is there any other option to check which is the the merge strategy with ScriptRunner?

Thanks.
