What that means is, if I look at the first example below BoxSize is expecting an integer, but in the model that it is running on now, it is formatted as a text parameter.  The data type must be the same in all models.

Error Examples

• An error occurred during export processing: ArgumentException: Input string was not in a correct format.Couldn't store <18x8.5x80> in BoxSize Column.  Expected type is Int32.
• An error occurred during export processing: ArgumentException: Input string was not in a correct format.Couldn't store <87.2cm - 34.3inch> in Width Column.  Expected type is Double.

Resolution

To resolve this issue, you will need to edit your models or families to get the custom parameters consistent in all the models, then purge the database.

Following the database purge, parameters don’t have their data type set yet and we start fresh again, but the same rule still applies. 

Process

In each model replace the parameter with the correct parameter so the data type is the same as all other models.

Once that is done in all models you can try rerunning the exports, but it is likely you will need to purge the database and rerun the exports.

How to Purge the Database

From the Project Home page, select the Pencil/Checkbox in the upper right and Edit Project

Purge Database

Yes

Rerun the exports.

Alternate Option Skip Tables in the Database

If you want to skip certain tables to get around the issue, please refer to the following blog.

Error
That error means that the file is too large to send back to the host via http so the config file needs to be modified to allow for larger file sizes.

Task Error
There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded.

If you exceed the default maximum file size which is 400000 you will need to fix a config file to accommodate processing larger file sizes, or enable uploading in chunks (preferred method).

Resolution Options

Preferred Method 

On the Task Server

Enable Upload in Chunks

Make sure the Clarity Task Server is fully updated

Log onto the Task Server as the designated Clarity Account.

1. Exit the Clarity Task Tray by right clicking on the Clarity icon in the Windows Task Tray and Exit
2. Through File Explorer Browse to C:\ProgramData\IMAGINiT Technologies\Clarity Task Server 202#\ClarityTaskService.config
3. Right click on ClarityTaskService.config and copy, then paste into the same folder.  Rename the extension to .ORIG as shown below
   1. 
4. Edit the ClarityTaskService.config in Notepad
5. Toward the bottom of the file, locate the line:
   <add key="UploadFilesInChunks" value="False" />
   1. 
6. Change its value to “True”.
7. Save the file
   1. If you get an error saving the file, save it to the desktop
   2. Make sure the save dialog shows All Files it is still seen in the screenshot and Append extension is not toggled, then save
8. Move the file back into the original folder and overwrite
9. Restart the Task Server Tray from the desktop icon Clarity Task Tray for Revit
10. From the desktop icon "Launch Task Server" for any version of Revit and make sure it picks up tasks

Alternate Methods on Host 

You can modify a config file to allow for larger file sizes.

To change the Config File

1.  On the Host Server, browse to the following folder:  C:\inetpub\wwwroot\CentralWebServices

2.  Make a copy of the Web.config file and rename it to Web.orig in case you ever need to revert back to the original file.

3.  Modify the:  Web.config

4.  Change the highlighted value below between the "400000".  Please make sure that you make the max request length high enough...perhaps go up to 800000

Example

   <add key="AllowOverrideTaskParams" value="No" />

  </appSettings>

  <!-- specific config for allowing large uploads to the Task Webservice -->

      <system.web>

      <!-- max Request Length, in KB -->

      <httpRuntime maxRequestLength="800000" executionTimeout="600" />

    </system.web>

   <!--

5.  Save the file, if you get an error about saving to the original folder, do a save as to the desktop.  Make sure to match the settings below before saving. 

We do not want anything appended to the end, so make sure that is not checked.

6.  Drag the file from the desktop back into the original folder and overwrite.
