could not finish module import, import loop count exceeded

dimitrios1988

Hello,

I am trying to import to a docker instance (the one you officially provide) an application that I exported, but I get the error "could not finish module import, import loop count exceeded". I have tried importing another small, app that I made for testing (just to see if the bug is coming from the platform), but the import was successful.

Can you please elaborate what might be wrong?

Please go to the logs view (admin panel -> logs) and raise the log level for "Transfers" to "Everything" (click on the "settings" icon in the top right). If you then repeat the import attempt, you can see everything it does in the logs, including possible errors.

If there is a direct error during import, it would have told you during the attempt. Some errors however could be resolved during import of a dependency and it therefore continues the import attempt for a while (eg. it runs multiple loops). If the error is not resolved in the end, the import will fail - which is what happened here.

Please take a look at what errors it throws, it will probably tell you what is wrong.

Btw. here is the troubleshooting documentation for your case. You might find useful notes there.

I read the documentation before I posted here. The error is the same. No other info. The instance I am importing to is brand new. I only changed the postgresql version to 17 to match the version I have from the machine I exported the application from.

If the log level had been raised before the import, you would see hundreds of log entries. Please redo the import attempt and then re-check the log.

We need that information to troubleshoot further.

I am just seeing in your screenshot that the log level is raised to "Everything" for "Applications" - are you sure its set to "Everything" for "Transfer"?

It seems from the logs that it can't get a function name by ID

"skipped entity on this run, error: failed to process entity IDs, failed to get PG function name by ID 82540e5f-0302-47fc-a3be-ffdc4b84be4f: no rows in result set"

I have dynamic query generation in this function, which made me write the schema name by hand (not with rei placeholders). Does it matter? I tried putting the whole function in comments, but I still get the same result. The function is called by using the rei placeholders and also calls other function (which also fail) using rei placeholders

gabriel

If the dynamic query generation is the cause I cannot say without seeing the code. It definitely makes a difference if you use placeholders. It might work, but without placeholders, r3 cannot parse what´s inside your function and things might go kaputts later when you rename something.

To test whether this function is the cause, remove the affected code completely - even functions in comments are parsed so they can still break things.

The function that was causing the problem was not the one with the dynamic queries. It two functions calling each other

Function A calls Function B
Function B calls function A

I merged the two functions in one and now the import is working!

gabriel

Usually cross-calling functions should work fine, but I´ve never tested a complete circle (eg. both functions calling each other directly).

I am glad that you found the issue and thank you for reporting back 🙂
