Hello @anchorrrr,

We appreciate your contribution. It seems that the text2chakra Converter is outdated. The schema has been updated to v0.0.4, and you can find the detailed description in the Chakra Schema v0.0.4 Release Notes. We need to update the text2chakra converter to reflect these changes, specifically by replacing the 'parent' field with the 'data_dep' field.

@anchorrrr it would be great if you can update this PR given the feedback / pointers from @TaekyungHeo. Please let us know if you have additional questions. Thanks!

Hello, @anchorrrr

Wish you have a good day! I might covered this in #78 by changing parents to data_deps, and also fixed some other bugs in the text converter. Could you please check out the PR and leave any comments if you like? Thanks!
