Seems like this error is intermittent and happens when all the MYOB APIs are enabled. It could be that the MYOB local Service is overwhelmed and raises an internal error.

I have been able to re-produce the issue by bombarding the MYOB API with multiple API calls all at once, however, when we throttle the API calls, the error does not happen.

1. The change will be available in version: 14.60

2. The following changes were made(Include Database object names, Program classes, and any other relevant information):

1. Added a flag named: "General Settings.DelayBetweenAPICalls". Default Value 1000 Milliseconds. This will allow 1 call per second throttle for all API's under this integration.
2. Added a flag "XXX.URL.GET.LastReadDateDelay". Default value 60 seconds. This is the amount of time (in seconds) to delay between API calls for a specific module. Recommend the following settings:
   1. For Masterfiles - set this to 600 seconds (10 minutes). If your Masterfile changes very frequently, use something like 120 seconds (2 minutes)
   2. For Transaction files, recommend this value to be 60 seconds.

3. Affected Areas:

1. Integration API calls where there is a throttle limit

4. The issue was caused by:

1. Throttle Limits on API from external systems

5. Other Relevant Notes:
