Description of the issue

Hello, I am using the codeql using VSCode extension. I want to generate AST for a particular file but it just won't show me the AST. Please note that I can view the AST for some files(majority of them) but for a few files I am unable to do so. All these files are present in the CodeQL Database that was generated. I have verified from the src.zip file. There is no error when I click on CODEQL: View AST button on right click in my src file in both working and non-working cases.(I've added logs at the end of this issue) I have attached Images for the extension tab when It generates an AST and when it doesn't.

Hi @aaaayush-n 👋

Do you have the logs for when you created the database (i.e. ran codeql database create ...) and, if so, could you share them?

[aaaayush-n]

@mbg I do not have the logs when the database was created, It was a long while back. Is there some other way I can help?

Some options:

• If you are able to share the database with us, we could have a look at it to see if the cause is evident from it.
• if not, there are some log files contained in the database that you could share with us instead.
• You could regenerate the database and share that log
