This page lists the most common Iguana errors, explains what they mean and identifies Actions to take.
This page is not definitive, to get the the best out of it you should use it as a guideline – or as a basis for your own list. You may have other errors that occur on your sites that you want to add to the list. Also you can customize Actions and Comments to meet your specific needs.
The list ErrorsOutShow.csv is available for you download and customize.
Please have a look at this post on how to document error messages. It shows how to export errors from Iguana logs into a SQLite database. The errors on this page are generated using the code from this FAQ. You may also be interested in this post How can I document Iguana Error messages – and create an Action Plan for errors that occur in the Iguana logs.
What do the fields in this table mean?
- Message: this is the text of the error message.
- Type: this is the type of error message.
- debug: this is a development coding error (for a programmer).
- Lua debug: this is a Lua coding error (for a programmer).
- error: this a legitimate production error (for an administrator).
- warning: production warning (for an administrator).
- info: information message.
- Status: this is used to decide which errors are shown in the filtered output (ErrorsOutShow.csv).
- show: indicates to show in the ErrorsOutShow.csv file.
- currently show is used to indicate unique messages.
- Other codes like hide and duplicate are descriptive.
- show: indicates to show in the ErrorsOutShow.csv file.
- Source: where the error into the was sourced from, e.g.,
- Interfaceware Log Export.
- Interfaceware – manual entry.
- Location: this is where the error is found in Iguana, e.g.,
- Iguana Logs.
- ServiceErrorLog.txt.
- Iguana System.
- Description: a brief/precise statement of what the error means.
- Comment: use to describe the error.
- longer brain dump of potential issues solutions etc etc…
- Action: a brief/precise statement of the action to be taken when the error occurs.
- You may require specific action(s) for your installation.
Note: *** is used when the exact meaning of an error is uncertain.
The list is divided into two parts. The first part General Errors does not contain any coding errors (Type = “Lua debug”). The second part Coding Errors contains a sample of (the potentially infinite number of) coding errors.
Part one: General Errors
| Message | Type | Status | Source | LogSource | Location | Description | Comment | Action |
|---|---|---|---|---|---|---|---|---|
| ‘PID’ member does not exist. Named members are MSH, NTE, PATIENT, ORDER. | debug | show | Interfaceware – manual entry | *** | Iguana Logs | PID segment not found in the parsed message | The parsed message does not contain a PID segment. This can happen if you write code that expects ADT messages (works with ADT) but then a different message arrives (ORM for example) and the code breaks. But an ORM has a PID segment – aha but the VMD you are using only recognises ADT messages – therefore the PID segment in the ORM message is not parsed – therefore we get the error. There are several ways to handle this write code to IGNORE messages other than ADT – or if you want to process ORM message tehn write code to handle them (and probably change the VMD so you can parse them – though this is not mandatory as you can write code to handle them in Lua without VMD parsing). | Debug code and fix error – could be incorrect VMD also |
| ACK query response has been inactive for 1 minute. | error | show | Interfaceware – log export | ACK query response | Iguana Logs | no ACK response for 1 minute | if this error occurs regularly it should be investigated | manage – fix |

It either does not exist, or the user Iguana is running under does not have sufficient permission to access it.\r\n * Directory into which processed files are moved is invalid. It either does not exist, or the user Iguana is running under does not have sufficient permission to access it.\r\n * Directory from which files are read is invalid. It either does not exist, or the user Iguana is running under does not have sufficient permission to access it.\r\nPlease edit the channel configuration to eliminate these errors.\r\n | error | show | Interfaceware – log export | Introduction – HL7 to DB – Txt | Iguana Logs | *** | *** | Create directory or fix permission issue |
| Couldn’t parse date ‘19580829000100.0-400’. Required format is YYYY-MM-DD or YYYY-MM-DD HH:MM:SS | debug | show | Interfaceware – manual entry | *** | Iguana Logs | Incorrectly date time format | This error is caused by trying to map an incorrectly formatted date time. You can use the fuzzy data parser to fix this. It is very possible that this may be a “data error” as most values are correct – with a few in the wrong format. | Correct the data time format (try fuzzy date time parser) |
| Created sub-directory ‘D:\logsindex’. | info | show | Interfaceware – manual entry | *** | ServiceErrorLog.txt | logs directory not found – created | index directory was not found. This is not a major concern because it will be rebuilt when it is not found. However, if this is a system that has been up and running a while I would question why it was removed | no action needed – you may want to investigate the cause |
| Created sub-directory ‘D:\logsmeta’. | info | show | Interfaceware – manual entry | *** | ServiceErrorLog.txt | meta directory not found – created | meta directory was not found. This is not a major concern because it will be rebuilt when it is not found.

Probably forgot to commit a first milestone for the channel. Solution: create a milestone. If main() is really missing you need to create that and then a milestone. | Probably commit 1st milestone (create main 1st if it does not exist) |
