Failed to compute diff between source and target schemas, error: failed to parse and preprocess old statements

[pkExec]

Provide the Bytebase version you are using

2.14.1

Describe the bug

I tried using the schema sync in the hosted version, was getting 502 errors.
So I tried the same in self-host version and I got the same error, but this time I could see this in the docker logs:

Failed to compute diff between source and target schemas, error: failed to parse and preprocess old statements

Followed by what appears to be a schema dump of the entire database.

The schema diff is being done between 2 databases on the same instance. Both are PostGIS-enabled databases if that makes any difference.
PostGIS version: 3.4.0

Steps to reproduce

1. Sync Schema
2. Select source schema
3. Select target databases

Expected behavior

Show Schema changes

Provide the database you are using

PostgreSQL 12.16 (Ubuntu 12.16-1.pgdg20.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, 64-bit

Provide the version control system you are using
