This error also occurs if you use four-space instead of two-space indentation.

e.g., the following would throw the error:

fields:
    - metadata: {}
        name: colName
        nullable: true

whereas changing indentation to two-spaces would fix it:

fields:
  - metadata: {}
    name: colName
    nullable: true

In my case  the error occured when I tried to pass a variable which was looking like a bytes-object  b xxxx   but was actually a string   You can convert the string to a real bytes object like this   foo strip  b    replace    n     n   encode

I would like to make this answer for meaningful  so the same kind of   erroneous user can enjoy without feel any hassle    Actually  i was getting the same error but for the different reason  in my case I didn t used any kind of quoted  still getting the same error like expected  lt block end gt   but found BlockMappingStart   I have solved it by fixing  the Alignment issue inside the same  yml file      If we don t manage the proper  tab-space Keyboard key   for   maintaining successor or ancestor then we have to phase such kind of   things    Now i am doing well

The line starting ALREADYEXISTS uses     as the closing quote  it should be using    The open quote on the next line  where the error is reported  is seen as the closing quote  and this mix up is causing the error

YAML follows indentation structure very strictly  Even one space tab can cause above issue  In my case it was just once space at the start    So make sure no extra spaces tabs are introduced while updating YAML file

With YAML  remember that it is all about the spaces used to define configuration through the hierarchical structures  indents     Many problems encountered whilst parsing YAML documents simply stems from extra spaces  or not enough spaces  before a key value somewhere in the given YAML file
