StringNotationToMapNotationIntention - NullPointerException

[Vity01]

I don't have some piece of code to reproduce the problem, but I hope it helps.
Plugin version 0.6
Intellij Idea Ultimate 2020.3.2

EDIT1. I think it's somehow related with a editing Groovy code in the README.MD when you mark code section as groovy, eg. :

README.MD

|```groovy
|  some piece of Groovy code   
|```

@Vity01 thank you for reporting this 👍 . I can reproduce it and I will fix it.

@platan how it's going? There doesn't seem to be much activity in the repository 😔

@0xfaulty @Janmm14 Thank you for reporting this. Did you get the exception while editing a *.gradle file or a *.md file?

[0xfaulty]

@platan Exception does not occur so often, and I was unable to reproduce it on purpose, when it appears next time I will try to describe how got to it.
But as far as I remember, it wasn't necessary to edit the *.gradle file, it was enough for it to be displayed, for example, by the search window (Find in Files) for the project.

[0xfaulty]

@platan got stable way how I face with this exception
Tested on latest (at this time) Idea version 2021.2.1
I use multimodule project if that matter (not tested in single module gradle projects)

1. need to add several lines in different place of *.gradle file (idk maybe just one enough)

In my case these lines:
    compile "io.springfox:springfox-swagger2:${project.swaggerVersion}"
    compile "io.springfox:springfox-swagger-ui:${project.swaggerVersion}"
    ....
    compile project(":common")

2. Git>Uncommited Changes>Stash Changes for stash these changes
3. Restart idea and wait for indexing complete
4. Git>Uncommited Changes>Unstash Changes then press View button and open changed file
5. Then press << arrows to appy changes one by one
6. Close that unstash windows
7. (!) icon should appear with exception

@0xfaulty Thank you for detailed description. I was able to reproduce it easily.

I've just released a new version 0.6.1 which fixes this bug. The new version should be available in JetBrains marketplace within few days.
