OC FAQs and Errors

The error states that there are specimen characters like +-/*(){}%, whitespaces (space, tab, newline, carriage return, etc.) in the CRF name. The OC connector uses the OID as the form name. These special characters are not allowed in the DE form names, hence the error.

Also, when importing the OID mapping CSV file, make sure that the column ‘OS_FORM_NAME’ does not contain any special characters.

For example, a form name can be added as ‘PATHOLOGY_DATA’ and not 'PATHOLOGY DATA.'

Fix: Clean up the CRFs to ensure they don't contain special characters mentioned in the log file in the CRF.

The error is displayed when the DE form ‘PATHOLOGY’ for the event ‘BASELINE’ is not yet created; hence the data cannot be imported. It would help if you made sure that the form error is fixed and imported.

The error is displayed when the participant was created in Open Clinica with PPID ABC01, deleted, and recreated. It would help if you cleaned up the mapping tables to remove the mapping of the deleted participants.

This error occurs when the configured server URL, Username, or Password is wrong. To fix this, check the below details and update if needed in the server configuration.

• Configured URL of OC in REST API Invoker.

• The username used in the configuration should have access to OC.

• Password used in configuration should be in a working state.

To fix these details go to REST API Invoker >> use the ‘PUT' HTTP request >> ‘Resource URL’ as 'ServerURL/rest/ng/or-server-configs/{configured server ID}’

Open

Once you update the necessary host, username, and password, click on 'Send'. You should get 200 status as a successful result.

When forms get corrupted due to any possible reason, this error occurs. In this case, you need to delete the existing form and resync the data for that form. Run below API to delete the form in OpenSpecimen.

1. Invoke the REST API using either Postman or HTTP client.

   <app_url> : Server URL where the forms are available. 

   {FormId}: Form identifier for which you are getting an error. Get this from the #2 step.

   <username>: OpenSpecimen Username 

   <password>: OpenSpecimen Password

2. Form ID can be retrieved from DB using below SQL

    

   select identifier, name from dyextn_containers where name = '<form_OID>';

form_OID: You will get the form OID from XML of CRF from OC.
