Drone Pull Request nad Push webhook failing when special chars in comment


I’m using Bitbucket Server v7.21.0 with Drone v.2.12.1 and I have problem with synchronizing Pull Request or building pushed code.
I figure out that the case is when I use some special characters for example colon “:” in commit message or in Pull Request Message drone build has failed.

The same code without some chars in comment is working properly. I was also trying with newest version v2.16.0 but the problem is the same.
Please help, it distrurbs developer work.
