Unable to generate apk because of invalid keystore format

Question

I have done all the steps correctly for generating apk file for my react native project as it is written in the documentation. But unfortunatly I am getting the below error. Although I have deleted my keystore and then generated a new one still I am getting this error.

Task :app:packageRelease FAILED

What went wrong: Execution failed for task ':app:packageRelease'.
