This can be caused by an issue which allowed incomplete or corrupt dxp files to get saved to disk or to the TIBCO Spotfire library. There is a fix that is released in the TIBCO Spotfire Server and TIBCO Spotfire client hotfixes which introduces validation during saving to prevent this issue. The related fixed issues are:

• TSS-22405 - TIBCO Spotfire now validates transferred content while opening items in the Spotfire library as well as transferred data when using Information Services if both client and server supports that.
• TS-54780, TS-54773 - TIBCO Spotfire now validates transferred content while opening or saving items in the Spotfire library as well as transferred data when using Information Services if both client and server supports that.

To avoid this issue moving forward, apply the hotfixes relevant to your Spotfire version on both the TIBCO Spotfire Server and the TIBCO Spotfire Analyst client:

• TIBCO Spotfire Server:
  • TSS_7.12.0 HF-001 or higher
  • TSS_7.11.0 LTS HF-004 or higher
  • TSS_7.10.0 HF-004 or higher
  • TSS_7.9.0 HF-004 or higher
  • TSS_7.8.1 HF-010 or higher
• TIBCO Spotfire Analyst client
  • TS_7.12.0.59 HF-001 or higher
  • TS_7.11.0.79 LTS HF-004 or higher
  • TS_7.10.1.13 HF-007 or higher
  • TS_7.9.1.17 HF-008 or higher
