codemod upgrade-legacy cause path errors

What is the problem?

When I try to upgrade legacy-framework (v0.45.5) using codemod, I get some wrong path errors

Paste all your error logs here:

  steps.push({
    name: "create blitz-server.ts and blitz-client.ts setup files",
    action: async () => {
      let appDirExist = fs.existsSync(appDir)

      if (appDirExist) {
        const templatePath = path.join(
          require.resolve("@blitzjs/generator"),
          "..",
          "..",
          isInternalBlitzMonorepoDevelopment ? "templates" : "dist/templates",
        )
        const blitzServer = fs
          .readFileSync(path.join(templatePath, "app", "app", "blitz-server.ts"))
          .toString()
        const blitzClient = fs
          .readFileSync(path.join(templatePath, "app", "app", "blitz-client.ts"))
          .toString()

        const replaceTemplateValues = (input: string) => {
          let result = input
          const token = `__safeNameSlug__`
          if (result.includes(token)) {
            result = result.replace(new RegExp(token, "g"), "blitz")
          }
          return result
        }

        fs.writeFileSync(
          `${appDir}/blitz-server.${isTypescript ? "ts" : "js"}`,
          replaceTemplateValues(blitzServer),
        )

        fs.writeFileSync(
          `${appDir}/blitz-client.${isTypescript ? "ts" : "js"}`,
          replaceTemplateValues(blitzClient),
        )
      } else {
        throw new ExpectedError("App directory doesn't exit")
      }
    },
  })

What are detailed steps to reproduce this?

1. clone legacy-framework)
2. $ cd legacy-framework/examples/auth (maybe anything with examples).
3. npx @blitzjs/codemod upgrade-legacy

Hey @kyken, thanks for the issue. The quickest workaround would be to use beta 15 of the codemod that still uses the app directory.

npx @blitzjs/[email protected] upgrade-legacy

The issue can be solved in the following way:

- const blitzServer = fs.readFileSync(path.join(templatePath, "app", "app", "blitz-server.ts")).toString()
+ const blitzServer = fs.readFileSync(path.join(templatePath, "app", "src", "blitz-server.ts")).toString()

- const blitzClient = fs.readFileSync(path.join(templatePath, "app", "app", "blitz-client.ts")).toString()
+ const blitzClient = fs.readFileSync(path.join(templatePath, "app", "src", "blitz-client.ts")).toString()
