Extracting next engine consistently fails

[dlculver]

When I run the WebAgent class to do a task, I consistently run into the following kind of error:

ValueError: No next engine found in the text: **Thoughts:**

* The current screenshot shows the Google homepage.
* The objective is to find the weather in Los Angeles.
* Since we are on the Google homepage, we can use the search bar to find the weather information.

**Next Engine:** Navigation Engine

**Instruction:** Type 'Los Angeles weather' in the search bar and press Enter.

Sometimes this issue is so persistent that even after several retries the error continues. I think this is because the extract_next_engine utility function expects to see things like 'Next engine' and the regular expression search is case sensitive. One option would be to ignore case when doing the regular expression search. I think this should be an easy fix and would also like to volunteer to fix it.

hi , @dlculver facing the same issue , do you have a fix for this ?

@DecentMakeover The way I solved it for myself, at least locally, was to find the particular file in the pip installed version of lavague. To get the location of lavague you need to run
pip show lavague
and you should see where those files are located on your computer. Change your directory to the location you found, and then open up the file lavague-core/lavague/core/utilities/format_utilities.py or something on those lines (don't exactly remember). Next, find the function extract_next_engine, and then what I did was change the re.search on line 170 to include re.IGNORECASE. Save the file, and then it should be fine (at least it was for me).

@dlculver, I have the same issue. I will try your fix locally, but what do you think caused this issue to arise? I was working on a project, and didn't run lavague for several weeks. The version in my project is pinned, so not sure why this just popped up for the first time.
