AWS Lex web browser checksum error [SOLVED]

If you are getting the following error: the checksum value doesn't match for the resource named {theNameOfYourIntent} in AWS Lex web browser console, on building after feeding intents, try the following:

1 (kind of optional) - Make a backup of your intent information in a TXT file (in case you lose your progress, which didn't happened to me twice)

2 Delete the intent

3 Create a new intent

4 Search existing intents

5 Load from a list the exact name you had

6 Build again

7 repeat in every case it happens with another intents

It solved my problem.
